Setting wives/gfs up to cheat (UK)

[Handiwerker]

I am interested to find out how many others have been so turned on by the thought, knowledge or actual evidence of their partners cheating ( in some sexual way beyond just a kiss) that they have secretly set up a situation to encourage it to happen?

I will admit the whole idea is a tremendously stimulating concept for me after I discovered a past gf did cheat ( but I never told her I knew), so much so that I set her up a few times after....... and enjoyed the outcomes more than I would have originally imagined someone would whose partner is having sex with another guy.

For me the trigger is the other guy being dissimilar to me, ..a friend or mate or someone so alike it would make it hard to see why she cheated.....( leading maybe to a feeling of loss or inadequacy or emotional upset). Hence and since her original cheating was with a teen boy a few years her junior; I have 'encouraged' similar situations with younger, fit, even mixed race boys.

What do others feel about this or indeed have been there and without her knowledge, set wife/gf up too?
