check out my post on clubbing/dancing kiss closes it covers an extremely easy way to get a girl to kiss you in clubs. the only drawback is you have to be dancing so you have to get her to the dancefloor first and once you do that you can kino her like crazy and use small micro escalations to build her up to being ok with kissing you.
relatively it usually takes 5-10 minutes of dancing but if your in a rush or wanna sarge on ive field tested it and done it in one song of dancing you just have to build her up. check it out heres the link
