It seems like for the first few years, all they want to do is have sex with as many people and as often as they can. Were you one of those people? I really can not say that I was.
I think I was when I was around 18- but that was 7 years ago. I think a lot of people, nowadays, seek out the validation that comes with having sex with a lot of people. Some people use it as a way to feel good about themselves. But once you gain confidence on your own and start to feel better about yourself without other people- you really don’t need that lifestyle anymore.
