When gender plays a role in your connection to the students

In my theory class, I have two boys (both sophomores) in my class. One of them has a 504 plan, the other does not. One boy has an incredibly bad attitude and is a bully towards other students. He does OK in theory, but he is having a hard time understanding the concepts of minor scales. When I approached him about it and asked him when he was available to come in for extra help he snickered at me and blew me off. I figured that he was just getting frustrated and that I would give him a day to cool off. So, I approached him later in the week, because he was still confused, and he ignored me and mumbled comments under his breath. So I looked up his 504 and saw that he has a tracking teacher whom is in charge of him when problems arise. I went to the tracking teacher, told her my issues with him, and she said, "no matter what you do you won't succeed because you're a woman. He gives all of his female teachers a hard time. He doesn't listen to me. I don't know why they assigned him to me. They should have assigned him to a male tracking teacher since he responds better to men." My student never turns in homework and doesn't participate in class. When I assign class work and I walk around the room to check on peoples work, this particular student takes his hands and covers up his work so I can't see it. I don't know what to do. I can't change my gender. My co-op basically told me that there's nothing I can do. When I ask for advice everybody tells me, "you can lead a horse to water but you can't make it drink." I'm so sick of hearing that. I have to find a way to make the horse drink, but in a different way. I feel that I'm at a complete standstill though, because it's my gender that's the issue and not my ideas or teaching. Does anybody else have a student like this? Does anybody have any advice?
