What do I do...

Devyn
When me and my fiance first started dating we were really romantic and pretty much all over each other. And for the last couple months he says I haven't been sexually attract to him. It is not true at all I try to make moves an I get denied. But if I don't want to have sex right when he does its to bad. He says our relationship is in jeopardy. What do I do to get my sex drive back or show him I do love him like that... so lost
