I'm just curious, can someone give me an answer?

I just want to genuinely ask because I see a lot of contradictory on this app. I just want to know. Why is it if a woman thinks her man is cheating, that's called intuition and they should trust it but if a man thinks his girl is cheating, then he's projecting and probably cheating? I don't want to offend anyone I just want to understand that thought process. Is it that men don't have intuition? Or are they too dumb to know when they're cheated on and only say something when they are the ones cheating. I just want to know why when someone thinks their partner is cheating one is intuition and the other is projecting? I seriously just want to understand
