Find a fwb for wife

Look i know it is strange.
But i been married 30 years
I love my wife.
She has cheated on me a few times but not the past 10 years
It turns me on thinking of her sneaking around on me. I can’t share this with her because she would not understand.
Would love to find a guy to seduce her somehow.
Is this too fucked up?
Not to steal her away just a fwb
