When you both feel really ready for sex, you'll both probably know. If you're all worried about it, then maybe the time's just not right yet. And if the time is never quite right with this guy, that can be sad, but it's certainly not the end of the world. Maybe that just means there is someone else you're supposed to wait for.

And I REALLY recommend talking with him about birth control before you do have sex. And using it. And if you aren't comfortable enough to talk about birth control beforehand, that's another BIG sign that this might not be the time or the person.

I do recommend waiting until it is someone very special to you. My first time was with just a friend 'cause I figured I might as well get on with it. I don't recommend that. It didn't feel very good, inside or outside.
