Too turned on...

So lately I've been extra horny, even when it's unnecessary, when I see my boyfriend we always tend to go at it more than 4 times in the course of hours. But I'm still left horny, even when my boyfriend has pleasured me. It's not that I'm unfulfilled, it's more like I want more sex, even when it hurts after a couple of times. I don't know what to do anymore, I masterbate and have plenty of sex but my arousal doesn't calm.
