Some girls will pepper spray you for asking for directions while others will accept a date after a few sentences. When you meet a girl for the first time, sometimes you have to pander to the worst-case scenario and be conservative in your approach, at least initially.
Just go up to one of them and say, "I wonder what your cock feels like inside of me..." And leave them with that. It will give you a huge edge over all the women using ambiguous flirting signals like eye contact and hair twiddling.
That should help get some of them to ask you out. Or you can just ask them out yourself.
