“Free condoms!”, “Safe is sexy!” These are words I continually hear myself saying, among others. And its nothing strange, for the most part. Its nothing uncommon for women to say “I’m on the pill” or for somebody to carry a condom in their wallet (although that is not advised), or purse, just in case. But, believe it or not, it hasn’t always been this way.

Have you ever thought about the history of your contraceptives? What were the made of? What kinds were there?

Well, in 3000 BC (Yes, BC! The same year that Troy was founded), condoms were made out of linen cloths, fish bladders, or other animal intestines.

In Ancient Egypt, there is evidence that a contraceptive device made out of crocodile dung, sodium carbonate and honey was inserted into the vagina to block sperm.

Other rumored methods include sponges soaked in lemon juice, ingesting mercury and using Coca- Cola as a post sexy spermicide.

It wasn’t until 1838 that condoms were made out of rubber. And the first oral contraceptive wasn’t introduced until 1960! Thank you Margaret Sanger.

In Ancient times, Papaya seeds were also used as a type of oral, male contraceptive. If eaten daily, they could cut a man’s sperm count to zero, and if not eaten for a long period of time then the sperm count would return to normal levels. And it’s been rumored that this information, along with others is being used for the creation of a male version of the birth control pill!


Hello everyone!

My name is Kristina, who also goes by the sexy name, Klassy Kristina! I am a 2nd year undergraduate with an intended major in Public Health at Cal. As a new SHEP sexpert, I am excited to be a part of the Sexual Health Education Program, which is a great resource provided by the Tang Center. I decided to take on the initiative to join this enriching program because I believe that sexual health education is crucial to a healthy lifestyle, especially in college. Growing up, I never had the chance to learn detailed and well-rounded information pertaining to sexual health in both school and at home. As a new SHEPer, I am more than thrilled to be educating others about healthy relationships, contraception, sex positivity and much more! I know that sex is a topic not widely discussed in many communities, but this is my chance to inform others about what it means to have and maintain great sexual health. With this being my first semester working as a SHEP peer educator, I know that there is a lot for me to learn but I am also grateful for the opportunity to be sharing my knowledge on sexual health with the Cal community. Not only is this a learning process for myself, but for my fellow bears as well.



Hi Y’all

I’m currently a second year @ UC Berkeley. I’m an intended Public Health major, and I want to create awareness about various sexual topics. Yes, this means any topics having to do with SEX. I am currently part of the Sexual Health Education Program @ UC Berkeley. I decided to join because I myself still have a lot to learn about sex. Most importantly, I joined because I want to create a community that is sex positive. I look forward to sharing my experiences as a SHEPer with y’all.



Hey y’all,

My name is (Booty) Brandon and I’m excited to be a part of SHEP this year! I’m currently a 4th year studying Integrative Biology and I’ve really enjoyed my time here at Cal. I decided to join SHEP because I previously worked with another sexual health program and I really enjoyed my time there. It was a lot of fun meeting new people, promoting healthy lifestyles, and handing out condoms! I’m totally looking forward to working with my fellow Sexperts and helping out my peers through random acts of sexiness!

When Should I ask for Consent Pink

We’ve seen a lot of different ways to talk about consent. You might be thinking, “Okay, okay, yes means yes, let’s get going.” But we’ve been talking about it so much because it’s the most important part of any sexual encounter. In fact, it’s important in any kind of interaction. You don’t want mustard on your sandwich, but the person making your sandwich does it anyways? You speak up and say that’s wrong. So why is it any different with consent?

It shouldn’t be.

Consent is the conscious agreement to a proposed action. There are some rules with consent that we’ve covered before: consent for one thing doesn’t mean consent to another; consent can be rescinded at any time; consent isn’t permanent; consent is not received through coercion or from someone unable to consent.

But let’s get into it a little more.

Let’s talk about the “enthusiastic yes!” You and your partner should always be ready and willing to do whatever activity you’ve decided on before and during that activity. If that feeling is not happy, excited, eager, prepared, or some other form of pleasure, you should stop and address it. If someone isn’t comfortable with something and doesn’t convey that explicitly in words but their body language says otherwise, then “maybe that’s not a no, but that’s definitely not a yes.”

Always make sure that all partners are consenting! “The communication of that, verbal and nonverbal is clear and constant. This is consent, and wrong would be the absence of that in any context for any reason.”

To put it in another way, check out this great video from Button Poetry on Youtube (that’s only a little over 4 minutes) called “Consent at 10,000 Feet.” I’ve quoted it a few times in this post because it’s that awesome! It looks at consent through a slightly different lens than what a lot of people are used to. Here’s a fantastic quote from it:

“Have you ever had sex while skydiving? Like where you talk about consent the same way you talk about wearing a parachute – no gray areas, no assumptions, like, ‘Yeah, I’m pretty sure I’m wearing a parachute, no questions.’ Like, I asked her to check my parachute and she didn’t say anything but it was okay last time so I’m sure it’s good this time, too.”

Just as important it is to have a parachute EVERY time you go skydiving, it’s important to get consent for EVERY sexual encounter! Respect your partner(s) and their boundaries, and stay safe!



Check it out, the female anatomy is just like the male anatomy. Just one is internal while the other is external.

First of all, the outer lips are also known as the Labia Majora. Now, it wouldn’t be a show without the inner lips or Labia Minora also showing up. It’s understandable for their names to be misleading however both labia’s come in a variety of shapes and sizes. The outer lips usually have the pleasure of being covered with pubic hair. While the inner lips usually remain hairless. These characteristics make every Vulva unique!

What do I mean by Vulva? We all have been lead to believe that the external part of a female’s anatomy that includes the labia majora and everything inside them is called the vagina; however we are here to correct that mistake. Actually, the external part is called the Vulva. Now, there are these incredible internal parts that extend inside the outer lips and around the vulva that is purely a sexual organ. Can you guess what it is? The CLITORIS. Yes, this beautiful organ is protected by the clitoral hood and it’s the most sensitive of all human body parts. That’s 8,000 nerve endings. Amazing right!

Anyways, the Vagina is part of the internal part of the female’s anatomy that is in the shape of a canal leading to the cervix and uterus. When the vagina is not sexually aroused it’s approximately 3-4 inches long however, when excited, it expands to 6-8 inches. Inside the front wall of the vagina is that magically spongy tissue called the G-Spot.

On the other hand, the male anatomy starts with the tip aka the Glans, it’s protected and lubricated by foreskin (if uncircumcised) and contains approximately 4,000-5,000 nerve endings. When the penis is sexually aroused, the Shaft, will fill with blood and become erect.

While, the Scrotum, is the sac that holds the testes. Males have the magical ability to draw the testes towards the body or drop them lower to regulate their temperature to 94 degrees Fahrenheit for sperm production. Cool right!

So, what produces the sperm? Surprise…Surprise. The Testes are in charge of producing sperm and releasing testosterone. However, the epididymis which sits on top of the testes, matures and stores the sperm. During ejaculation, the urethra is the tube that carries the semen out. It also carries urine from the bladder however never at the same time. Did you know that one ejaculation may contain 40-600 million sperm and that amount of semen can vary from a few drops to an average of 1-2 teaspoons?

Then, does that mean men also have a magical spot? YES. Direct stimulation of the prostate through the anus has been found to be pleasurable for many males. This magical gland is often called the P-Spot.

At the end, Show and Tell is never over. Need a physical representation? Check yourself out.


One the biggest parts of sexual health is knowing what’s normal for you and your body – have you ever taken a good look at what’s going on down in your pants?

It’s likely that you’ve seen anatomical diagrams for what male and female genitals are “supposed” to look like, but bodies are all different; some parts might be a bit bigger, some smaller, maybe some are shaped a little differently, and some don’t fall under the classic “male” and “female” diagrams. It’s important to know what your own body looks and feels like so that you detect any signs of changes that could indicate problems, which could include STIs or other infections. It can also help you find which areas feel more sensitive to stimulation and which don’t (sexual pleasure is a natural bodily function, and it can have lots of benefits!).

There are several ways to make sure your body is staying healthy: self-exams, clinician appointments, clinic tests, and general tracking of your body’s functions. Self-exams can help you understand your body’s natural state, and if you perform them regularly (say, in the shower or when you’re changing clothes), you can notice any changes that might occur. Self-exams include visual and manual checks on your breasts and/or genitals – check for any abnormal lumps, discoloration, swelling, pain, or STI symptoms. If you do find anything unusual, remember to stay calm and consult a clinician before jumping to conclusions. Regular clinician checkups give you the opportunity to discuss any health issues or concerns you might have, and clinicians can conduct physical exams and procedures (including STI tests if you’re sexually active) that they’re trained to do that you might not be able to. They can also instruct you on how to perform self-exams if you’re unsure. Even if you’re not sexually active, checkups are important – especially if you have a family history of certain conditions (like breast, cervical, or testicular cancer).

Keeping track of how you function on a regular basis can lead to questions that trained clinicians can answer easily for you – and remember, sexual health is just a part of your overall health! So know what your body looks and feels like – whether it’s through checkups, self-exams, or some self-lovin’ – and don’t be afraid to schedule an appointment if you think something is wrong. Know what’s normal for you, and stay healthy!


On this day ,Wednesday September 9 students explored both the external and internal anatomies of male and female bodies. Though this may seem like fundamental knowledge it was important that this particular section come before we begin exploring other topics. It is remarkable that students go through formal education without learning the parts of their own sexual anatomy or of their counterparts. I myself , must admit that learning the parts of my own internal and external anatomy came in my later teenage years and in fact I learned male anatomy before I learned my own. THE PATRIARCHY?!!

We began our class section with an Ice Breaker called “Move your Ass…”. During this activity students actively engaged in conversations surrounding  sexual preferences,activities, practices or procedures etc. that they engage in while attempting to get their peers to “move their ass” in the process if they to engage in this said activity. Afterward,it was clear that  we grew more acquainted with our students. We will definitely utilize this activity in future class meetings!

Furthermore, It was imperative that we presented on the external and internal anatomies because often times in middle school health curriculum students don’t get this information, or when they do, they may have difficulty due to how awkward it may be to discuss these ideas with other adolescent peers. Proclivities to discuss sex at this age are common but repressed. This has dire consequences that may prevent youth from obtaining vital information that may ultimately save their lives. Students learned that there are 16 , YES 16 different Contraceptives. My fellow Sexpert Jamee presented on these  and provided crucial background information for each of them including the chemical responses that transpire when taken, how often it should be taken and the general consensus surrounding each form of contraceptive.

I am very confident that students left our section with a better understanding of their bodies and varying ways in which they can engage in healthier sex practices.

Next class section we will dive into the following topics : Sexual Debuts and Healthy Relationships. Let the SEXY LEARNING CONTINUE !

Be Well,


Female Anatomy


Consent is simple, yes means yes and no mean know, right? Not exactly.  Consent is a little more complicated than that.

To clear up some of the confusion, here are 3 things to remember about consent:

Consent to one thing, doesn’t mean consent for everything.

If you go to Subway and tell the employee you want provolone cheese on your sandwich, and the employee puts on American cheese, youre going to be a little angry, because you asked for something and you got something you didnt want.  If you hear your partner(s) give consent for provolone cheese, and you give them American cheese, you have violated their consent.  Thats why its important to listen to your partner(s)s consent and ask questions if you are confused.  It also helps to be specific when communicating with your partner(s), dont just tell them you want cheese, tell them what kind!

Consent now, doesn’t mean consent later.

Lets say you are talking to your friend, and your friend asks you to scratch a part of their back they cant reach and you decide to comply.  This doesnt mean you can run up to your friend any time and scratch their back or any other part of their body whenever you feel like it.  The consent only counts once, and you need to get consent if you want to repeat an event.  

 Consent isn’t permanent.

At any point in time, a partner is allowed to change their mind and modify or revoke their consent.  For example, I could consent to going running with a friend, but at any point during that run, if I feel unsafe, exhausted, uncomfortable, or any regret, I can change my mind and we will stop running.  You are always free to change your mind, and you should be careful to listen to your partner(s), just incase they change their mind.  

So remember, yes does mean yes, but it doest mean yes to everything, it doesnt mean yes to any time, and yes can always change into a no.  The key to nailing consent is communication.  Talk to your partner(s) and decide what your boundaries and comfort levels are.  It is always better to clear up any confusion with questions that to proceed without certainty.  
Stay safe and sexy!


I’m feelin’ myself, I’m feelin’ myself- I’m feelin’ my, feelin’ myself.

Feeling yourself? GOOD! Because it’s good for you!

For a long time, we have been told that masturbation is unhealthy because it can cause blindness, and even infertility. In addition to these rumors, there is also the social stigma that surrounds masturbation within social settings like family and friends. After all, masturbation feels so good and here are the reasons why:

  1. It reduces stress: through masturbation, dopamine is released and this chemical helps control the brain’s reward and pleasure centers, and thus reduce feelings of stress.
  2. Reduces perception of pain: when one orgasms, they release another chemical called, endorphins. This chemical decreases your perception of pain. This means that masturbation for women can reduce menstrual cramping.
  3. Cures colds: One study found that in males, components of the immune system are activated during masturbation, increasing the number of white blood cells in the bloodstream so you will not feel sick again.
  4. Makes you fall asleep faster: prolactin is a chemical that is linked to sleep. So when one masturbates, they release this chemical and will induce feelings of exhaustion and will then have the chance to catch up on some sleep.
  5. Increase sexual performance: Both men and women have pelvic floor muscles that stretch from your pubic bone to your tailbone. When we age, these muscles weaken and cause sexual dysfunction in women and erectile dysfunction in men. However, stroking the penis or clitoris can activate the bulbocavernosis reflex, resulting in pelvic floor muscles contracting. It’s basically a workout for your sex muscles.
  6. Self-love increases the quality of sperm: a study showed that male masturbation reduced the number of sperm inseminated at the next copulation, but not the number retained by the females. From this, it was concluded that masturbation is a male strategy to improve the fitness of their sperm, as younger sperm have a higher likelihood of insemination.

While masturbation has its physiological benefits, it is important to switch up your techniques. Using the same hand to masturbate can make you sexually unresponsive to other types of stimulation. This means a decrease in sexual arousal, or sexual performance when you encounter a sexual experience with a partner. So light some candles up, play some music, and have fun!
