My wife knows this is a fantasy for me, we’ve been married 22 years, I’m her only dick she’s ever had. When I tell her about the fantasy she gets turned on during sex but then asks why I would want that.

That’s where I cant explain it in a way that she knows it’s ok and what I really want. She thinks it’s due to me not wanting her anymore or me wanting other females. Which is not what I want.

So what can I say when we aren’t tipsy and having sex and role playing it to explain that I really just want to see her pleased and experience another man and that there is no other motive? Guess I’m just unsure how to discuss it to make sure she can go through with it.
