Why must i beg for sex

Okay so ive been with my guy for over a year now, in the beginning I was the top and topping me was out of the question.

But as time went on I started getting REALLY turned on when he would act dominant towards me, like shove me into a wall for a makeout, or pin me down, or bitting my neck so hard it would leave welts.

Now this was a little weird for me considering im just naturally the Alpha in my relationship, but having my guy be more dominant and forcefull was beyond my control.

After a while I was the bottom, every night hoping to be woken up by incersion lol. Then I couldnt seem to blow him enough I always want it either in me, or my hand or my mouth no exceptions.

But then my lust went outta control the night he made me cry, now it wasnt tears of saddness or pain or anything like that, it was just overpowering euphoria. Ive NEVER cried from anything feeling TOO good.

And now I NEED it everyday, he gets annoyed and says we mess around too much. He messes with me now cause he knows ALL of my buttons so he turns me on and kinda giggles when I squirm from just wanting him.

Now is it normal that I want it like 4 times a day?
And should I be worried he doesnt want sex as much as I do?
