No, I don't. I've been bullied by other females before, but... I've been bullied by guys too, so I guess I feel more or less the same about both guys and girls. Gender isn't important, and I rarely HATE someone (though I might feel a strong dislike for some people at times).
I think I am more shy when it comes to guys, though. I might find them a bit intimidating, and I don't mean that they come off as scary/violent (though they might do that, too), but I feel nervous about aproaching them and stuff. I might feel like that with girls too, but I think it's worse with guys. I also think that I'm not close to many people who are male, I think it's mostly females I've gotten close to. So yeah, I find females less intimidating, I guess.
...Actually, I believe I've never thought about that.
