Yes, it IS all about who the person is today, rather than yesterday. Well said Fagunwa.
However, I would want to know the motivation behind doing a porn film - money, ambition, ego, and how that person views the act (and art) of sex.
If sex is just a commodity to them, then no, I'd run in the other direction.
I can understand people making home-porn, but doing it commercially (to me, anyway) lifts it into a different level altogether.
Once sex is a commodity or performed like an auto-response, I feel we become lesser people who've lost touch with our souls AND our sensuality.
Sure, adults fuck, it's why and how they fuck that counts.
My 2 cents.
