My girlfriend and I have been dating for ... 3 weeks now. We are very sexually active, however therein lies the problem. She cannot seem to climax either orally, manually, or during intercourse.She says that this has been the case with all of her boyfriends and I should not worry. I'm not particularly worried at the moment, but I have a vested interest in being able to please her in any and all ways possible, as I really like her and would like to keep her around. So I'm seeking possible alternative means to accomplish my goal.Additional information that may be useful.She can orgasm by herself and masturbates regularly.She is still rather young, 18 (this may be a factor?)She has several fetishes (all as a sub) which I have been very happy to accommodate.Again, if you have constructive suggestions, then please by all means give me some potential advice.
