OK my boyfriend is 20 and I'm 19... I want to know what I can do to turn him on. there are times that he's not in the mood and I cant get him in the mood. Also after sex I want to go again and he just cant. I try grabbing him and he gets hard and we start to have sex and he gets soft even while we are doing it. I don't know if it's that I'm not getting him excited enough or being sexy enough. I want to know how to really turn him on? Also how to make him want to have sex again ? And how can I make his orgasm more powerful? help
