I am 23 and have never done it, I've never even been on a date or had a relationship. In fact I've never done ANYTHING. I understand what you mean, I do daydream/fantasise about it a lot, and I get really envious of people who have relationships and have sex. But at the same, if the opportunity did arise, I wouldn't do it, I really want to wait. So it's that fight between wanting to wait, and being tooooootally desperate.
