Did I take it all too far?

I am openly lesbian and recently spent a week away with my dance troupe. I spent most of the time chatting with Andy, 21, and his dance partner's husband Liam, 29, who I barely knew before the week away. We had some really good laughs and they were both 100% comfortable with me and even got me out of some awkward questions about my sex life from some overly inquisitive teenagers. Then, on the Friday night, the place we were staying held this disco, which was a nice relief from all the structured dance practice. After a couple of drinks, I was a lot less shy than I normally am, and I went to dance with Andy and Liam. It got a bit up close and personal with Andy, to the point where it would have been rather inappropriate had I been straight (ie blatant flirting mixed with quite a bit of grinding). It was all just a bit of fun, but I noticed the teenagers looking concerned/worried/creeped out. He has a girlfriend, but he said that she won't mind because I'm gay. But do you think it went too far? Should I say anything to the teenagers? (I'm 18 btw)
