How to be dominant?

I want to beat the shit out of my husband.

In a sexual way...

I’m 5 weeks postpartum. I’m horny as hell. Whenever we start getting intimate, a deep but not so serious anger emerges. I just want to beat the shit out of him. He’s 6’3 and I’m 5’2 so that’d be hard to hurt him. I use to be the timid submissive one. Now I just want to fucking dominate him. He smiles and looks drunk on hormones. I just want to fuck him like my life depended on it. He loves when I’m angry. I feel like I might go to far or like it too much? I don’t want to turn into a bitch. I’m a polite artistic type generally.

What do I do? how do I start?
