Is it normal when i j/o sometimes i rub or slap the head of my cock on my ass.

I'm a straight white male but interracial Porn turns me on so much.. big black cock gets me so hard..when I start to j/o while my cock is getting hard I can slap my asshole with my head or just rub the head around. It feels really good especially with a lil lube...iin??? And I also think about sucking black cock alot
