Attractive.. Asshole?

So I'm extremely confident with my breasts and vagina but.. My butts a little different. I love anal and anything that has to do with the back door, however, I hate how I look and it stops us from experimenting. I'm a very pale girl with pink nipples and vagina but my butt is brown and.. Purplish blue??(my skin in so pale it just looks like lots of blood flow to the area) Im an extremely clean person. It's always been that way. My partner has a cute pink butt and I can't help but want the same. Is there any way to get this without bleaching?? Or do you just have to be born with a pretty butthole??
