I live with my girlfriend, and while not the same as with a non-intimate girl, I think there is a universal thing going on: guilt. If they're dirty, disgusting slobs or love bringing people over too much, you can say little things that make them feel guilty. In most cases, it will work unless the girl is a terrible human being or male. Example: Dishes in the sink been there a while? "Man, the kitchen's beginning to smell. Is there anything dirty in there?"
so have you roomed in yet with these girls? whats the update? when will www.stipendlaxsexyroommatesnude.com be up and running?
IMO, living with chicks is a lose lose proposition. if you hook up with one or all of them, there will be drama. if you don't hook up with them, you will feel like the gay best friend. and if anything ever goes bad, they will band up against you because that's what girls do.
