My boyfriend has pratically zero sex drive
I've been with my man for 5 years, and we have 2 children together. He is 10 years older than I am. Initially, we had an awesome sex life- neither of us could get enough! Now, my feelings haven't changed, but his have dramatically altered. He lives like a priest when it comes to me, but browses porn online. He claims to love me and be very attracted to me, but all I see is him avoiding having sex with me. We do it maybe twice a month. To me, that is unacceptable. If I mention that, he goes all stressy on me and says I'm too demanding!
I don't have the worlds highest opinion of myself, but I'm not unattractive. Is it normal for him to say I'm too demanding because I want to be intimate with my partner at least once a week? Is it normal that I can walk around in a tight black corset and panties in front of him, and that his reaction is annoyance that I'm in the way of the television?
