@Reyaj, you could be right...you could be wrong, as John Lydon once sang.
If by "loyal" you mean a woman is less likely to ride a random c0ck just because the opportunity randomly presented itself, maybe that's true. A lot of men would probably cheat if they knew they'd get away with it, or if the opportunity were thrown at him. Women get c0ck thrown at them 24/7.
But always consider the power of slvt shaming, which when not a deterrent for women is at least a silencer. I've been with women with boyfriends who wouldn't even breathe a word of the fling to their supposed BFFs.
I also believe there is an infidelity spectrum and some girls just reside on the wrong end of it. Yes AWALT but some women are more prone to cheat. My ex cheated with me on her then-BF. I don't doubt she did the same on me. Then again, I wasn't that into her and didn't show much "loyalty."
