I wouldn't unless it's someone I trust. Only because I don't want my ass getting fucked being put on public display. I'm more about it being a novelty of memorializing a good fuck.
Funnily enough, I once got fucked by a "porn star"; in quotes because he didn't make many movies. Stage name was "Vixen" from latinboyz.com. Even though he bottomed mainly in his vids, he was more of a top. While okay with shooting porn videos; he wasn't cool with recording him fucking me. Just as well; I didn't really enjoy his dick. That and he smoked a lot of weed; started giving me a headache.
