> I'm a female dev and I don't feel weird on all male teams. Just another team member. But I did feel singled out when the other female developer and I were mostly assigned to work together.

Could it have been to make her feel more comfortable? With certain jobs I've had, my male co-workers would communicate differently with the other males than they would with me. Sometimes they'd talk to me like I was removing my training wheels, other times more formally, and other times less seriously. This changes with time (well, okay, not sometimes), but that was the initial approach.
