Every women is different in her experiance, some women don't feel any pain, for some its a whole lot. I would sugest missonary as well, but i will make an aditional suggestion... lots of foreplay for her, and go slow slow slow, that way if it is painful you can stop... one thing i hear a lot is guys just assuming it is suppose to hurt and the girl just has to deal with it. he gets so exited and she is very freaked out... that is not a good experiance. My first time i experianced the almost make you pass out pain but my partner was not pushing me and stopped right away. we slowly spent a week working to make it better before we really had "sex". You just have to take it slow and easy and get feedback from her.
