My husband and I started out with a fantastic healthy sex life... Of course of time it's diminished a bit. Well tonight we were doing it and I could not climax it took me so long to achieve orgasm from oral which normally is no problem. Then during intercourse while it felt great as soon as we were done he was immediately grumpy and complaining bc I pulled away a bit when he finished & it got in the bed. My question is, is it normal for our sex life to become boring and Unenjoyable?
