Please help me. What should I do? Will God still Accept me?

I'm attracted to men. I'm bi. I'm attracted to women as well, but what really hits me is men. I have fetishes, and I feel like I could forget them, but I can't. Every time I get close to a guy, I feel like running away to resist the temptation but I can't. I would pretend I'm in a fantasy and I would ejaculate. I try to pray every night, but I end up praying every week. I want to change, and to be pure as I can be. I'm a Christian. I need help. Can someone help me please?
