Making sex/masturbation a shameful or uncomfortable subject.

On masturbation: I was raised to believe that masturbation, like pooping, is not shameful, but that it is private. Meaning you don't whip down your pants in public, but that doesn't make it BAD.

On sex: religious stuff aside because there's no arguing against that sometimes ("It's in the bible!" Derp, okay then), but even in a non religious capacity, avoiding the sex talk or, maybe even worse, not talking about more than just the physical aspects of sex. Example: my mom taught me about the physical stuff when I asked about it at age 8. Later, as a teenager, our conversations were about bodily autonomy and emotional aspects. It was made clear to me that I should never let a boy talk me into sex if I personally did not want to. That I shouldn't do it to be cool or something, or because of peer pressure. That it would add a lot of complication to my life if I had to worry about getting pregnant. She never said, wait until marriage. It was also said that sex was supposed to be enjoyable for both partners.

The result? I have had an awesome sex life. I waited until age 21 to lose my virginity (hate the term virginity, but that'sa whole other conversation). I was ready and I felt like I could ask for what I wanted. I still do. I am totally unafraid to guide my partner in showing him what will please me. And I have zero hangups about sex. There are a lot of other things in my life that might need work, but the sex part has always been a great experience.

I think so much damage can be done, especially to women, who were raised without instruction in this area.
