It's interesting how different people are... my friend would have licked the guys face, I wouldn't. And if he'd done it to me I'd probably have slapped him.
Watch - how did you know he was into the lick? (this is nothing to do with what happened subsequently, I'm genuinely interested). And maybe jealous that noone has ever given me 'lick' signals 
I met a man in a nightclub and at the end of the evening he went to kiss me on the lips, I turned my head. This was nothing to do with not fancying him, I fancied him loads, but I just didn't want to do something intimate with someone I didn't know. I ended up marrying him (not that night you understand
) so the spark was there.
My DH hugged me on our first date but we didn't touch other than that till we kissed on the 3rd date. Been together 6 years so definitely a spark there and again I really fancied him and wanted to kiss him but waited for him and he was quite shy so ended up taking a while - Although, and maybe he is a sexist pig, I know he'd done things on first dates before (everything but full sex I think) with people he had no intention of seeing again. Maybe he has a madonna/whore complex?
Just really interested in how people do it differently.
