threw up on his dick!

So I've been friends with this guy for a very long time. Last time we slept with each other I pushed him off me. It was one of those "I don't want to ruin the friendship". 
It's been a while since that happened, I went over a couple of nights ago, we made out. Then went to his room, I actually wanted to have sex with him this time. But I was on my period. So we made out some more. Then I went down on him. He started doing what guys do, and pushing my head down. I fucking hate when guys do that. 
Any who, he did it enough to where I threw up in my mouth. While I was sucking his dick. All I can think about is, if he thinks I'm nasty for doing it. 
Afterward he finished, and we went to sleep. Should I expect him to want to have sex in the future? 
This probably makes no sense but I have no girl friends that I can ask, or talk to about this. How should I feel about this?
