I need to make her have an orgasm
Me and my girlfriend have been dating for a while now. I am 19 and she is 18. We have been having sex for about four months. I can't seem to make her have an orgasm and I have been using every position that I know and every trick I know. I am not new to sex and orgasm and every other girl I have been with I have made them orgasm and I know that because of the signs that they have made. I want to please her in bed and she says the sex is great but also she has never had an orgasm and I want to be the first to give her that. Any advise on this will help me out a lot any tricks or tips positions or whatever works I just want to please her and make her happy and I don't want to be like some guys that their girls leave them for another guy because they don't make them . But I just don't understand why I can't make her when I do everything right but also she won't let me go down on her but help me
