well, have you ever fucked someone and was complaining that you are horrible, i am not sure, sometimes hairy guys are so hot, but not like your matter, it is really the first time that i hear about hairy ass cheek, actually it is still look like sexy, put in your mind that some girls like hairy men more than any thing in this universe... ask an expert...
i am not that hairy but some girls asked me if i had shaved or not and if so they would love me to keep lots of hair in my body spatially in fiki fiki stuffs.... hummmmmmmmmmm....
dude dont worry, you are normal, and if you dont like your hair on ass you can try to get rid of it for ever by laser operations... its is kind of expensive but it does work!!!!
