Am I too horny for my bf?

A lot of the time I get horny around my boyfriend when we're cuddling half naked in bed. A lot of the time I get turned down when I gesture towards anything sexual happening in the moment. I'm often left feeling gross about myself for wanting it all the time and can't help all the thoughts that go through my head like "i'm such a slut" and "i shouldn't be upset that he doesn't wanna have sex" which makes me even more upset.

Am I a sex addict? Should I not be wanting it as much as I do with him? I thought guys were always down? Why am I so horny at the wrong times? Help???????
