Crossing over to the dark side! My first step into the world of domination

Married woman here. Husband and I have always had good chemistry and the man knows how to fuck! But, I am now looking to explore my own dominant side. I am not sure why is is surfacing while the sex is already great but I have slapped him in the middle of sex and he loved it. I have had sex partners before but he is the only one I want to dominate!

I would like to know how do you step into it? Like if I wanted to be his dom, how do I make the experience arousing for him? Does the man get aroused because you humiliate him with words and actions? I am scared that I may say or do something that would turn him off as this is not anything we have done before.

Can someone guide me into how to create the first bedroom experience as his personal dom? Thanks.
