So I recently moved to a new city and am in a group of friends that likes to go out to dance clubs on weekends. Until this year, I really didn't drink, dress up, or go to clubs but after being single since birth decided to change this. While I learned how to order decent mixed drinks and dress up, the actual dance protocol still seems elusive and I know that I've looked like a bad guy based on the way I've handled girls that were attracted to me.

As an example, my first kiss was with a girl on the dance floor while I was drunk. She wasn't quite my type but she approached me and kind of half-reached out her arms to dance. I obliged and as we dance she went in for a kiss. Wanting to be over the never-been-kissed hurdle at 24, I went for it and apparently did a pretty good job. She asked if I had a phone and when I pulled it out, she took it and put in her number. She then smiled and walked away. As she did, I realized two things: I could not remember her name and I still wasn't attracted to her. After that, I ignored a text she sent to me that night and really was at a loss of what to do.

Since I don't want to continue giving girls the wrong signals (a couple of other numbers have landed in my phone that I didn't want), how should I be handling these situations in a more gentlemanly way? I'm not trying to say that these girls thought I was really something but they were at least mildly interested and I feel bad about accepting their numbers. So what should I be doing? Refuse to accept dance invitations in the first place? Send a few polite texts?

tl;dr I don't know how to club and have no relationship experience to assist me in knowing what to do
