I am constantly amazed at how little men know about the intricacies of the female reproductive system and all the things associated with it. I recall sex education (back when kids got that kind of education) -- the girl bits and boy bits were discussed to a co-ed classroom. But while I was furiously labeling the vas deferens and fallopian tubes on my quizzes, they boys were clearly not paying attention after the condom and banana demonstration.
The guys I know don't understand scented versus unscented tampons. Most men don't understand why we have cramps, or the crazy variations in hormone levels women endure every month. They don't know the difference between a UTI and a yeast infection. And while that doesn't necessarily keep them from being good in bed, shouldn't men be a little curious about what goes on in our bodies, both when they're in there and when they're not?
My ex-boyfriend and I were on a road trip a few years back, and somehow I ended up jokingly reading him the packet of information that comes with every package of birth control pills. He turned down the radio as I informed him of the increased risk of blood clots I faced in my quest not to bear his children. I continued through the section about when to start the pills (if you take it on the first day of your period it's effective right off the bat; if you start on a random day, you need backup contraception for a month). When my voice started to give out, I put the book down and expected to listen to the radio again for a while.
"Why are you stopping?" He asked me. "This is fascinating. Keep reading."
Maybe we're just trying to educate the lads at the wrong age.
