I wouldn't consider it as doing "best", it's not a race or a competition, eh? :')
Kissing a girl on the first date isn't too much of a big deal - depends on how well (and long) you knew her before the date really and how the date goes, imho.
I wouldn't wanna make it to the bedroom though - if you're in it for the sex, why not just go to clubs and try and have one night stands with girls?
