When I was single, I only ever had one good female roommate.
I had many excellent male roommates. (Okay, some of them were toilet target challenged, but that's not a huge issue.)
Ironically, the biggest problem with female roommates was that I had to put up with their love relationships. (Whereas most of my male roommates, when they got a girlfriend, they tended to spend time at her place, giving me more privacy.) Even my only good female roommate, Judy-Venus, eventually presented with boyfriend-related problems. Her boyfriend wangled his way into moving in with us (he claimed the apartment he rented was being painted so he needed to stay with us for just a couple days -- he never rented any other apartment, it was just a scam!). Until he moved in, we lived peacefully and very cooperatively. We never worried a lot about who paid what bill or bought/ate which groceries. We did a lot of things together, but one thing I liked about Judy was that, if she wanted to go out to eat or to a movie, and I didn't feel like it, she was just as happy to go alone. She was very low maintenance that way.
We both felt comfortable that everything tended to balance out. But the day after he moved in, I came home and opened the fridge to find everything rearranged, and shelves labelled with our names! Not only weren't we allowed to eat *his* food, he decided that we shouldn't be eating each other's either (why it would matter is anybody's guess). He had rigid ideas about changing the decor of our home. And he seemed to need to control every aspect of our lives.
And, of course, it wasn't long before the fighting began. That was really pleasant! I moved out.
And the other thing is that, in my experience, chicks always want to discuss their relationships -- and if he won't talk to them, they'll go after the next available person = roommate! Every single female roommate I ever had dragged me into her neverending soap opera love life. This was never a problem with any of my male roommates.
So a lot depends on your personality. If you're the kind of person who gets along better with women than men, then maybe you'll be okay. If you don't mind having your roommate's boyfriend(s) become feature players in your day-to-day life, then maybe you'll be fine. Me? I'd live on the street in a carboard box before I ever lived with another woman again!
