Is it normal to be this demanding during sex?

Sooo, I am one of those girls that like to be dominated during sex and my hubby is completely fond of this. While we were having sex:

during missionary: I said "go slow," "okay that's perfect *insert his name here* ___," and he put my legs by his shoulders, and I said, "kiss my breast," "choke me."

during doggie: I said "spank me," "pull my hair," and he called me a bad girl.

While I was on top: I told him to "put his hands on my waist," then I moved one of them to hold my breast, and the other one to my throat so he could choke me.

during reverse cowgirl: he was doing some of the work and I said "keep going, don't stop ___"

SOOO, I didn't realize it at the time, but now that I look back I feel like I talked A LOT. I mean, I've heard of communication being a good thing, and I wasn't being rude when I told him to do those things, but I was just wondering if its normal to have this many preferences during sex.
