The only ( well for now) I would like to say is, if your are not thirty year old, super fit guy, then don't take a twenty five year old, sex goddess, you will stand out.
Try to play in your own league and look for opps there. I once met a late thirties couple on a quiet night, probably their first time in a club. I was thee only male who talked to them about normal day to day conversations, I ended up having a great time, the macho types, shaking their heads.
It can be a bit of a game and you have to pick it up as you go along.
