I've published a number of circumcision-related erotic stories ([Login to see the link], and in file uploads to this board, which you can find in my post history).
Along the way, I've met guys like me, who got to keep their foreskin and want every other male to keep his ... but who still get an erotic charge at the thought of their own imminent circumcision.
It might take a lifetime of searching to find a woman willing to role-play this, so I'm resigned to the realm of fantasy -- written material, and the occasional humiliation video. The challenge is finding well-written, well-acted productions. Porn and erotica don't attract top talent.
