In all cases, cheating is not about cuckolding about the fact that the husband cannot provide high-quality sex or anything else!
In my humble opinion, the wife (or even the husband) often needs something new, something different in addition to the usual and often considered safe factor.
It is very possible that my ex-girlfriend made our relationship unilaterally and discretely open precisely because of the novelty, which caused us to lose trust in each other, even though we had amazingly huge "sex battles" with each other! We tried many things, but he decided differently!
On the occasion of our last sex, he satisfied me orally and swallowed every drop of my sperm because I demanded it, and he did it in a powerfully excited and submissive way. Due to the ******* of dominance, I felt the fact of cheating was less humiliating, but rather viewed it as a kind of exoticism, and the intoxicating feeling of "now I own you, you cock-sucking whore" pervaded me.
Of course, the mutual, morally legalized cheating that forms the basis of the swinger lifestyle has a different emotional effect on a husband / wife than when it happens without their will and blessing and they are only faced with the harsh facts!
However, there are people with a masochistic spirit, for whom physical and/or mental pain causes excitement and a high degree of satisfaction!
