Rosanne, I agree with Lion. There isn't a problem as long as couples are on the same page.

The trouble arises when one partner isn't happy, won't communicate about it, and becomes resentful and angry.

I can't stand it when someone isn't happy with their sex life and they mention it after a couple drinks, humiliating their partner. How stupid is that? Then "the wife" says, "you're cut off". Well honey, when you cut him off, you're cutting yourself off too. I never understood that logic.
