The commonalities are locker rooms and hot tubs.
Around these parts, YMCA's are the number one pick up spots for homosexuals.
Hot tubs are maintained at a temperature of 104-108, a perfect incubator.
In my area, it'd be that the students themselves were gay or bi.
*shuddering*
Horrific thought actually.
And women go to the health spas here to pick up men, only to find they're all gay.
The real men are out keeping Bambi's population in check.
*sigh*
Sorry I didn't get back to this sooner.
