When Me and my husband are trying to make me orgasm,or he is stimulating my clitoris I can get really close to orgasm and sometimes I do orgasm but if he gets off my clitoris it dissapears and I have to start all over again.I also can't orgasm during sex.When I masturbate I can orgasm in 15 mins or less but when we do it together it takes between an hour or even two!!!Ive lost ALMOST all interest in SEX.Its killing my relationship.Can something be done?
