All the girls were probably at the gay bar. Back in Uni I was dating this girl who frequented gay nightclubs and bar so she wouldn't get hit on by guys. Apparently quite a few girls do this. You should try going to gay bars next time you're looking for sex.
I'm pretty darn drunk right now. Wife out taking daughter to play rehearsal... I'm not sure how many g+t consumes now. . XCOM and booze makes a great combination.
