My boyfriend of a year seem to have lost desire and being intimate with me. I am very confused because he's very affectionate, loving and sensitive with me. I gain, at most 5 lbs during our relationship. He stress that it's important for me to keep fit so he'll still desire me. When we have alone time, he always complain of stomach hurting, goes in the bathroom with laptop for a very long time. He says he's very sexual person and can masturbate after intercourse. When I brought it up to him, he makes me feel shallow and wanting sex. He's never passionate with me, he only went down on me once throughout our relationship!!!! I am confused because he's great guy in showing his love, attention and commitment towards but that still doesn't help the fact that that's as far as it goes. Should I stay? I am on verge of closing this chapter but need reinsurance that maybe it's a lost cause.
