The Problem With Too Much Sex

My partner would like to have sex twice a day every day. If we go eight days without sex, all hell breaks loose in our house. He picks fights and often says, you're really lucky I'm not the kind of guy who would have an affair. His explanation is that sex is the only way he can experience love and appreciation. Though he recognizes my contributions to our relationship, none of them really make him feel loved or connected to me. None make him feel safe. Is there such thing as wanting too much sex? And therefore feels entitled to mine? Please tell us what your thoughts are on this bizarre power dynamic.
