Let's put it like this - if I wasn't married, I would fuck Robert Redford no problem, he is still hot, if a bit old.
I think I wouldn't do it actually, I've had boyfriends in the past who demanded I shag them at the click of a finger and it's a traumatising experience to do it when you don't want to, having to block out what's going on to not cry. I think it would fuck up my relationship with my husband if I did that even for a million bucks. And if word got out that was how I got the cash, my parents would never speak to me again....
