Definitely makes total sense to try to find a real slut. I'm totally attracted by slutty women.
That's a big age gap both ways. That kind of age gap is a real turn on. Have you ever fucked one of your friends hubby?
I would advise being honest but firm and assertive. My ex told me that she wanted to experience other men and the she wanted me to stay faithful. It worked as I understood it was important to her happiness.
