what I wish was taught in schools about sex

I had "sex education" in 9th grade science class. It was mostly the biology of human reproduction, and nothing I didn't know already. What is far more important are the social and emotional aspects. 

Adults are reluctant to talk about sex in general and especially around children. Some oppose sex education because they think it will make teens more likely to experiment. I think the real reason is they feel embarrassed when they talk about it. 

Here's what schools should teach:

1. Fetuses have been observed masturbating in ultrasound images. Everyone experiences many orgasms long before they actually have intercourse.

2. The loss of your virginity will likely be a disappointing experience. 

3. Many people lie about their sex lives.

4. Stupid people boast of their sexual prowess to shame the intelligent and the gullible. 

5. About 20% of American men will have sex with prostitutes at some point in their lives. 

6. Smarter people have fewer children and have them later in life. They are also better parents.  

7. You'll lose money if you chase women, but you'll never lose women if you chase money. 

8. For every pot, there is a lid. 

9. Sometimes the juice is not worth the squeeze. 

10. Don't buy the cow if you get the milk for free. 

I think adults like having "secret" knowledge since they perceive that it gives them power over children. It's sort of like the Santa Claus mythos. 

If I had to put a number on it, I'd say sex with a woman gave me about $20 of happiness, and sex with a beautiful woman gave me about $40. $20 will get you a fast-food meal and a 6-pack of good beer with a few bucks left over. 

I'm short, shy, and have been fat most of my life. I'm probably in the 10th percentile for sexual attractiveness. Even so, I've dated many women and had a few girlfriends. My conclusion is that it's not that big a deal.
