I go to local salsa dance classes every Wednesday and there is a lot of attractive girls there that I'd love to chat up and ask out. Problem is, I don't know how to do it without coming off as a douche who is only there to hit on girls. I honestly started going with the intention of learning how to dance (at social functions I always look like a tool with duck's feet whenever I try to dance) but, well, these girls are hot, I'm not going to lie. But it seems like most people advise against it, saying that trying to hit on girls in dance classes will immediately out you as perverted creep. Yet I don't wanna just walk away from an opportunity to get with attractive girls that I already have some social connection with, I already spent most of my life shying away from opportunities that I dearly regretted later.

So, any advice?
