Sex or porn?

My fiancée seems into porn more lately. I get rubbing one out here and there is good but if I am in the mood and get nothing to find out later he watched porn when I supposedly went to bed it pisses me off more. Honestly everyone would you rather be woken up and have sex because you barely have time to as it is with two kids or just masturbate yourself and kiss sex life with your S/O good bye?
