Just chill, man. Obviously, there's too much pressure on you. Maybe you feel the need to "perform" in front of your girlfriend and that's why you're so tense and can't ejaculate (still better than premature ejaculation!). I say you guys buy Kama-Sutra or any other book with illustrated love positions. I'm sure you guys can figure out a way to do doggy-style, though. Use a chair or something. In a word, use your imagination.
