if they never try they will never get the girls.
are they afraid of being refused? Hell, in my times I got 4/5 "no" each evening at the "disco", so what? maybe with no. 6 it was a "yes"
it's just a matter of standing around holding a drink with a 17" arm at a bar
if no success, move a few metres to the side, and repeat
if no success, go to other bar and repeat
if no success go back to bar and repeat
usually there is some whores on your arms by this time
if not go home and fuck your girlfriend and repeat another time
