I was 17 and waited a couple of months into a relationship before having sex. There's no rush, trust me. There's plenty of time for intimacy. Don't feel you have to offer it up on a plate just to try and snare a guy. In my opinion, the right guy will respect you so much more for wanting to wait. You'll probably find that if you get to know each other first, most of your inhibitions and fears will disappear and things will just develope naturally
