Doctor,I am 18 years old,and my girlfriend is 19. We have a problem with defloration, she is experiencing great pain,and we've tried 10 or more times already. I know it is supposed to happen slowly,when the time is right,but my self-confidence is ruined. I've had sex before,but only with girls who weren't virgins,and it went ok,sometimes great. So,I know I am not the problem,(despite my errection problems at the begining),and it's still a difficult situation. What can I do to make it easier?
