Today, as a part of his lecture on sex and the brain, my Cognitive Science professor decided it would be appropriate to discuss what the effects are of sexual dimorphism in the brain.
Males, he said, have a much more difficult time controlling their sexual impulses than females. As evidence, he pointed out that erection and ejaculation are reflexes- controlled by neural circuits in the spine, not the brain (The same as a reflex in your arm- that's why you pull away from something hot before you even consciously realize it's hot.). This is true- but even if erection and ejaculation are reflexes, that doesn't mean a man has to have sex... except he said it means they do... which confused me, to say the least. He also said that women have more inhibitory circuits in their brain, so it's easier to stop themselves from having sex. And that's why we should all pity Tiger Woods, according to him.
Next he talked about sexual orientation and how it may be that because women have "more choice" about whether or not to have sex, being a lesbian is a choice, whereas being a gay man is not. By this point I was getting seriously annoyed.
Then he went on to discuss what men and women are better at. Men are better at spacial thinking, women are better at things involving language or color perception.
I was too upset to approach him after class today, but as soon as I can I want to ask him for some further reading on this subject. I want to see the studies that he kept referencing (but didn't name) and I want to try to understand their methodology. 
But here's the thing: my personal experience tells me these results just can't be right. My partner and I are a perfect counterexample to quite a few things he said. We both love sex but I honestly think I have a harder time staying monogamous than he does. I do it because I believe in honoring my promises, and I believe that what we have is too special to share, but some days it's hard, especially because we're long distance. He on the other hand has not the slightest trouble.
The evidence presented in these studies bothers me because they can be used as excuses for why men "just can't stop themselves" or why women "just shouldn't expect to like sex as much." They take the individual out of the picture and leave... what? Meaningless data, in my opinion. I reject these excuses. Not that I don't believe that my partner is special and unique- but come on guys, if he can do it so can you. Oh and women who love sex? Yeah, we exist.
Many of my beliefs rely on what is scientifically proven- for example, my belief that comprehensive sex education is a better solution than ab-only methods. So if reliable science shows this, I guess I'll have to say that yes, men and women are provably, biologically different. However, I will also insist that individuals are different. Women can be great at math, men can be amazing writers. Lots of women love sex. Lots of men know how to resist sex.
And if it is true that as my professor said, women have evolved more than men such that we have more control over our sexual behavior then I will turn back to my feminist friends and say, "Well ladies, I guess we need to find ourselves those rare few evolved men (you know the ones who understand seemingly simple concepts like the word "no," which science tells us is really not so simple!) and only sleep with them. It's for the betterment of the species, we're making sure any sons we have inherit such amazingly advanced brains!" 
If any of you have heard anything to confirm or disprove anything my professor said, please let me know. I'd be very interested to hear from you. As for me, I'm heading over to Amazon to get myself a copy of "He's a Stud, She's a Slut" now. Maybe after my professor gives me some further reading, I'll offer to trade ;).
