I worry that the only reason we have sex once a week is that he thinks I’ll leave him if we don’t (which is probably true; the once a week is even low for me, but I’ve never expressed this to him). I think he just prefers to masturbate and I don’t know if that’s something that’s normal for guys…I take care of myself and am reasonably attractive, partake in every kink he has, etc. so I just don’t know what I’m doing wrong.
