Beauty Spot / Birthmark on Butt?

I have a beauty spot / birthmark in the very centre of my left butt cheek. Its not exactly small - its the exact same size as a 5p piece. Its a medium brown color and flat to the skin. I am a little paranoid about it and especially worried about what my boyfriend will think of it. He thinks I have a good figure but hasn't seen this birthmark - and I am a little shy about flashing it out there! As a guy, what would you think? Would it be a turn off? Or would you not care?
