OK, to start, I have a cuckold fetish. So no judgement there. However I really don't understand how people genuinely get off on one of maybe the most painful things ever (getting cheated on).

Yesterday i posted an experience I had years ago, where I let my friend fuck my ex-girlfriend casually while I went out, and I can't describe how painful it was. I actually wanted to die for a while; i felt betrayed and defeated. And then the fetish developed. And then I was confused. It's one of my biggest fetishes.

While cuckolding does indeed include watching your partner being fucked in like a threesome or basic exhib, I'm more so imagining:

1. Knowing your partner is fucking/had fucked someone else
2. Your partner had/has sex with someone else in your presence and you find it shocking/uncomfortable
3. You partner fucked someone else while in the relationship and said they're better than you in some aspects

It's those sorts of things. I don't understand how someone could get off on something so painful, myself included. I grew up in a family of cheaters, too; I've seen over and over the damage it causes. So this one stumps me.
