Are you a good looking dude? Do you blatantly ask to bang them/take them home or disguise your intentions?
The thing with me is im not shy, now being shy isnt that bad but if your shy and you hide your intentions and then you go to kiss or make a sexual statement you become a "stalker" or "Freak"
Im more like Ari gold, the character in Entourage, witty, funny, cocky, but not arrogant, cause u will be alone if u act to good for everybody.
I dont blatantly ask to bang them, though i have done that when i was in qld and a girl was asking a random guy to leave her alone and i stepped in, then she was talking to me bout how her BF treats her like shit, then i just got with her and said "lets go back to my hotel and fuck like crazy" we did..
I find it so much easier to pick up girls when theres 3 or more, there more comfortable talking to a stranger when there in numbers, then i just work my magic and then figure out which girl will put out
