Sexual tension on the dance floor, or anywhere for that matter is simply fun. I enjoy dancing close with someone I find attractive, even if I am not interested in her, the playing around that there might be something there is still fun. I think most people enjoy that interaction. I don't see any reason why anyone should feel guilty about expressing attraction as much or as little as they are comfortable with. I don't think you should worry about other people taking things the wrong way, if you flirt with someone and they think you are interested, if they are interested or simply enjoying the interaction they will let you know it. At this point someone will up the ante, if it ever gets to a point where one party is uncomfortable with it or reading more into it than there really is it will come out. Basically what I'm saying is one shouldn't feel guilty about being flirtatious on the dance floor or anywhere else, this is supposed to be fun. Getting back to the hot salsero discussion I think it would be monumentally stupid to not date someone "because" they are a good dancer, or popular in the scene. I say give him a chance but maybe take it a bit slow, if he's interested enough he will be ok with a slow pace, or is it the slow pace will cause him to be interested enough, that's a discussion for another board.
