Having been married twice already, I already balk at the idea of getting married a third time... YIKES!!!
However, if would depend on the woman, really. Doesn't matter if shes a former pornstar or not. I'd have to get to know her and find out if what is in my head is the reality... but I'm gonna say that its a no. Fantasy and reality are VERY different, what we see on screen and what they are like in normal life are not the same, but damn it would be fun to play that up a little!
Would I date one? Most certainly. Would I marry one? I don't know, I just don't know.
