Whats the best way for a guy to take a girls virginity without her hurting?

Might be tough: It may hurt her no matter what you do, but in general, be gentle and slow and listen to her- let her guide you in terms of how to move and at what pace. Make sure you are using some sort of contraception too, at least a condom- not just to protect from pregnancy but to protect from STDs as well.

Slowly and carefully: Make sure she is in complete agreement with you about intercourse, or it will be a negative experience for both of you. Prepare by carefully creating a mood in which she feels loved and gently touched. When you are preparing to make penetration, make sure to have plenty of KY Jelly available. Go very very slowly, and if she asks, stop. Penetrate very slowly, gently easing forward. Go slow with KY.
