Anal virginity?

I posted it on my thread but it didn't get any attention.
Just curious what guys think about it.
If you're into anal would you want to pop someone's anal cherry?
If so, how much would you donate for it?

What would be the deciding factors in whether or not you were interested m?

Just an observation, How would one 'verify' that they were in fact the first to boldly go where no man had gone before?
