I once watched a program on E - I think it was that Dr 90210, or something like that - and it featured a porn actress going to get her anus/the skin around it bleached, to make it "appear better" on camera.

What I'm saying is I agree with the other commenter, don't judge your body/"normal" by what you see on porn!

I have the same issue, btw. None of my partners have ever complained. :)
