Is it normal for my butt to get wet like a girl when i anally masturbate?

I'm a male, and I like to anally masturbate with my fingers. When I do, my hand slowly becomes drenched in sticky, slippery, clear and white fluid that starts to come out of my rear, more coming out the better I feel. If I finger myself long enough, both of my legs, all the way down, as well as the rest of my lower body, starts to feel like there's a lot of pressure and tension in my muscles, and I feel like I get close to orgasming with my anal muscles instead of my penis. Though I can't seem to actually get to the final climax.
So I'm wondering if it's normal for the anus to self lubricate and give sensations like I get, or not.
