I imagine it is different for men and women. Should it be different? Not at all but in the past up until recently, advances generally come more often and more aggressively from men rather than women.
With that in mind, some men will likely take the rare time they get a pat on the bum or a crude gesture as a funny, complimentary advance (as shown by some replies in this thread
) if it was from someone who was not horrendously bad looking. I think if you were a woman, that advance can be added to the number of other unsolicited advances you have received and filed away under annoying because the guy is full of himself or full on harassment depending on the guys moves.
The times are changing and so are the attitudes towards courting but we still have a few old school attitudes when it comes to dating/relationships/advances.
