I've been dating this guy for over a year now. I just resent found out that he masturbates in bed. At first I didn't say anything because I felt embrassed. Now this is starting to annoy me because he does it everyday for hours and even after sex. I finally asked him about this but he says he don't remember. Please help I don't know if the is natural for a guy. I feel really hurt, angry and feel like he's cheating on me.
