I've been married for 2 years now, my husband has the desire to have sex with other women, but not me. He also imagine having sex with other women while having sex with me. He doesn't ever look at me anymore while we have sex too, he made it so damn awkward that either i have to close my eyes, or he turn and look somewhere else. I have not gained pounds, nor do we have any kids. What could be the reasons why?
