I have had both male and female. The female was as sweet as she could be but I hated sharing the kitchen. The male was better as he just came and left, basically stayed out of my way. The female wanted to be part of the family. Both were short term.
If I had my choice it would be male but I can tell you I was constantly worried about the male housemate. I knew someone that knew him a little but I was never comfortable as a single women with kids to have him in the house.
You just never know.
I wouldn't do it again.
