So, I'm going to start this off by saying I'm 20 years old, not some "old lady" who doesn't remember what it's like to be young.
I think sex should be freer and a lot less taboo than it is in our society today.
That being said, I had sex at fifteen. I thought I was ready. And I thought I loved the guy I was with. It wasn't a terrible experience by any means, but it wasn't at all what I imagined it to be. It wasn't glamorous, it didn't change my view on the world, everything was exactly how it always had been right afterwards.
All sex did for me was make me constantly worry about becoming pregnant. And I'm sure you realize that that's terrifying for a fifteen year old.
Looking back, I feel like I should have waited, at least until I found someone I really cared about--who cared enough about me to make sex special. Because sex should be a special, intimate, ultimately enjoyable experience. I never got that when I was younger.
