If it wasn't for YEARS of bad experiences, I'd be open to it. But I've had literally hundreds of immature girls playing males and ruining the RP. I used to allow them to play men all the times. I also used to do a LOT of lesbian RPs because I am a bi-demisexual. Sadly, the immaturity of so many of the women actually drove me away from both of those. I rarely do lesbian RPs anymore and I never let females play males as mains. 
It know women can play males, I just haven't gotten over the countless girls who ruined the roleplays playing them.

;-; Sowwy.
