Sex on mind

Is it weird that I'm always waiting sex. Like ALWAYS it's always on my mind and I've been like this for years ... I don't tell nobody how serious it is. I can control the urge to have sex but the thought is always there ... Especially with my current boyfriend. It's like I'm satisfied after sex but always wanting more. Like I never want it to end. Even when I can't even move I still say yes to wanting more.  Can I be addicted to sex ? Or do anyone else experience this
