I can only speak for myself but there are some very general ideas that make these things cut and dry.
Every human being has a Disgust Factor. We find certain behaviors, actions, ideas, thoughts to be disgusting. The disgusting is often a turnoff and engaging in it causes one to lose respect for someone else.
This is universal, across all human beings. You're a liar if you say otherwise.
Thing is: everyone's Disgust Factor is different. Mine is high, I know it is and I don't care.
I once talked to an older chick that had almost everything a nigga wanted. She was a little thicc, had her own spot, childless, intelligent, ambitious etc
One day, she was upset about a convo that she'd had. I was trying to smash so I listened. Turns out she was being harassed by this dude who kept calling and texting her trying to get on.
I laughed. I laughed until she said she had fucked him before and was ashamed of it.
I thought like all good white knights that it was no big deal...until she told me he was 16 at the time and she was in her mid-20s. Disgust Factor sounded and she almost immediately stopped being attractive.
She said all the same bullshit I read in this thread "I had my hoe phase, I'm not proud of it" yada yada yada even though it was almost 10 years removed from the act I was still disgusted and couldn't see her as anything other than a predator hanging out around High Schools.
I didn't flip on her, what I did do was back off though.
I don't see why i should be willing to sleep and share my life and bed with women I don't respect or that I know have done disgusting shit.
I don't want to, I don't have to, and I choose not to.
There's too many lonely women who don't engage in disgusting behavior, or at least have good enough sense to make sure the bones are buried under a garden.
