So confused.

I have literally masterbated everyday for two weeks, sometimes more than once. I will go for hours at a time or until I fall asleep. It's not that my SO and I don't have amazing sex, bc we do. I'm just never satisfied lately, even with me pleasing my self. I've even tried anal for the first time which was a bit painful but amazing. I have no clue what's going on, but I'm embarrassed to ask my partner for more sex. He's literally has a scab on him penis from having to much sex. But I want more!! What are somethings you do to satisfy yourself?
