So I’m a bisexual but recently I have not been wanting to have sex with my gf; my libido is way low & idk why. I haven’t had sex with a guy in a while & at the time me & my gf are trying to come out pregnant. We have a sperm donor but we don’t use him the natural way I guess. What I’m trying to say is, should I sleep with my sperm donor in order to have a better chance at getting pregnant?
