Dating one? Nah, fucking one sure (if I wasn't married)
But just imagine if everything goes well and you get serious, move in together etc. Then one day when she comes home, you sit down to eat and you ask her "how was your day honey?" and she replies "oh it was quite hard, the gangbang scene dragged on for hours, I was covered in cum for hours and they had to shoot the DVDA scene two times since the camera man fucked it up the first time".
I am not the most jealous man in the world or anything but really, that would not really make my appetite any better, nor would I want to kiss her afterwards.
