lol faggot.
Just kidding.
I'd say you're just conservative. Some people need to wait for it to be right. Unless, of course, you suffer from social anxiety... in which case you could be in trouble in the future.
As for smoking and drinking, etc. I know tons of people who don't do either.
I honestly wish I had waited a bit before losing it. I was 15. I wasn't ready for it.
But it did give me time to hone my skills.
