Hello! I need some advice over what else to try. I can't make my gf come when we are having sex, the only way she comes is through oral; she is not able to come when I'm penetrating her or when I finger her. Has any woman experienced something like that? We have try several positions and more foreplay before sex... at this point I don't know what else to try... I want to be able to make her cum while penetrating her ... any advice?
