is there such a thing as too much sex?

Okay ladies I need advice. I'm 20 years old and my sex drive is insanely high. My boyfriend enjoys sex a lot and we have it very often... but I feel like mine is to the point of being annoying. As soon as we go to bed I automatically think about it, and if I don't get it I can't sleep..I literally love sex. If he's tired and not in the mood I'm miserable. I feel like I have to have it.  I stay with him multiple days throughout the week and even days in a row, and I crave sex the entire time we are together. I masturbate like every normal woman should. Our relationship isn't based off of lust, I love everything about him, we've been together for a year and the sex is just amazing. Idk why I'm this way but I need advice on how to not be so turned on all the time!
