G.M guys
Lorenzo here with his first English number close, I feel pretty good but I don't know the next move because I didn't create rapport at all: I was with my group dancing and I went to the sexy bar tender with the first thing that came up in my mind and then since she was working I asked for the number.

got it, but what do i do next? I think I should call/text her soon because she didn't had the chance to know me, I couldn't create rapport, comfort and so on.

my question is; should I text or call? should I wait or do it right away?

looking forward for your replies

Lorenzo

I would call, and try to establish some connection in those five to ten minutes of conversation. Do it soon, before she has the chance to forget who you are. If she gave you her number, it means you passed the first level of attraction with her, otherwise she would have used an excuse like "Sorry, I cannot go out with the patrons of the bar, it's our policy". You have the number, now make good use of it... Good luck!

I like what Redlight says, but imo talking on the phone seems to be a lost art. I rarely get an answer if I call a girl I just met without texting 1st so I usually open with something creative that sparks her attention then once some comfort is built move into a phone call.
