I'm not sure. It could also be due to how they were treated in the past. If they've been treated poorly by one gender, they may prefer the other.
It could also be that Tobi just doesn't like me very much. She does let me pet her sometimes, on her terms, and will play a little game with me in the morning. I'll call her over to say good morning, and some days she runs right up and sticks her head under my hand. Other days she'll run up, then run out of reach again before I can touch her, then finally come over to me. Then other days she'll sit in the back corner of her pen and just look at me until I go get her morning treat. She only plays the game first thing in the morning.
Tobi doesn't like to be touched anywhere other than her forehead. When her sides or back are stroked, her whole body tenses up. She used to try to bite our hands, but now she just whips her head around and sticks her nose against the hand to let us know we need to touch only the forehead.
