Ok, so, I don't drink, smoke, do any form of drugs, and have never had sex. But, I'm still a pretty happy person.
I have many good friends who I can have fun with on a regular basis. I have a good summer job, and I'm heading off to University come September.
I'm only 18, so, in America, heading out to bar to drink isn't an option for me, and trying to sneak around my parent to drink or do drugs never really seemed to be worth the effort.
As for not having sex, well, its just never come up with any of the girls I know. I hang out with alot of girls, and my closest group of friends include 2 girls, (3 guys including myself) and we go out to movies, restaurants and stuff as a group. None of us are "involved" with each other, and that's just fine with us. We still have fun.
And when I'm 21, I'll probably go to bars and drink, and when I find the right person, I'll have sex. As for drugs, I'm gonna try and avoid that, as, of the people I know ho do use drugs regularly, they are pretty fucked up to say the least.
