הכרויות סקס חינם|סקס מזדמן

A very close friend of mine has tried to date with a girl and rejected ,surprisingly they managed to be friends

Recently i got a feeling that she is into me.I also think she is hot and even our nerdish interests are same ,i am not very much into her but saying i have no feeling would be a lie.

What kind of action is appropiate in a situation that she offers a date or if i try my chance,or is doing these even acceptable?
