It does not have to hurt. My ex loved anal activity and it was very exciting for her. I, however, experienced pain and swore to never let anyone do it to me again. Its probably mostly in your head, I don't find it stimulating no matter who is receiving.

I can't get through to her 'cause it doesn't permit
But I'm gonna give her everything I've got to give.

I hear your sweet voice calling
out my name
As I stare from a six foot cell
And from beyond I heard the words
Deceptively Yours
