That seems to have been the OP (in the GC thread's) experience and it didn't bother them much. I've also heard similar things from gay friends, as well as found the discomfort and difficulty of anal to be greatly exaggerated myself.

So I'll have to say that you'd still be portraying somebody's anal experience accurately.

(Unless "assholes" really do differ between the sexes, which defeat's the anon I responded to's point entirely.)
