Depends on whether they are single or not...
if the females are in a relationship and its going well, then it can either be fine. HOwever they can spend that time continuosly texting their partners or are always waiting for that booty call and they are off like a shot...
that goes for both sexes actually...
when they are single they tend to be more on the prowl and so forth.
saying this, there aren't many guys that i could on a one on one venture with and same thing goes for ladies...however, i would much rather go out with a group of guys than with a group of ladies. two chicks max (if there are no other guys).
