Im not sure if boyfriend ( 31) has lost interest in me or if maybe im just paranoid. Our sex life was great intell about a month ago. This hole month has been weird.. He is either to tired for sex or his stomach hurts etc. We are now only having sex maybe 2x a week. But he either nuts fast or he can't stay hard during sex. Wtf is the problem? I ask him and he gets mad if i ask if its me. Does it sound like he has lost interest?
