"I agree. I almost never go after a woman like that on the first meeting. Unless the woman has been very flirty!"
I guess some of this depends on what KIND of meeting we're talking about. If it was a meet and greet coffee date with someone I had very little contact with prior - then perhaps it would not be appropriate for a guy to hug me.
But if it is a two-hour date with loads of conversation and spark, with someone that I have had some long chats with prior to meeting - then I would think it odd if a guy didn't at least make a move to hug me. Granted, of course, that it has become perfectly obvious that we both like each other.
