Man, I vaguely remember my first time, and it literally took soooo long to get it up it almost didn't happen. It's just one of those things that you build up in your mind and when it happens it's so surreal that it takes time for your body and mind to sync up. I say mess around with your girl until you're about ready to pop, then take it to the bedroom. But yeah, you're not alone, and once that first time is passed, you'll be a sex machine.
