Because men are shit at identifying them when they rarely appear. If you're a little too aroused for their taste, a little too eager, or don't bleed enough, then you're probably a lying bitch and you belong to the streets. And then after the encounter you truly belong to the streets anyway so like congrats ruining yourself for one of the 80% of men who decided you were too good to not be a used piece of shit. This didn't happen to me, but it seems so common that I really wonder, for majority of women, what's the use in even trying when you're gonna get ruined by a guy who isn't even a bad person but loses his marbles last minute because of all the fearmongering and paranoïa towards women.
