Is cheating kink normal?

So, I’ve (M26) been with my partner for 3 years, and we’re good, no real complaints. But lately, I’ve been getting this wild itch I can’t shake. I’m constantly trying to talk to girls online and getting kinky… knowing I shouldn’t be doing it… fuck, it’s like a drug.

I don’t even know if I’d actually cheat IRL, but the idea of it crossing that line, getting away with something so wrong gets me stupidly turned on . My partner has no clue, and that just makes it hotter somehow. Am I fucked up for this? Anyone else get off at this or am I just spiraling into some wild kink? I need to know I’m not alone in this.
