I'm well aware that this increasingly popular saying is just classic slut shaming, but I'm interested in discussing the actual thought process behind this.

What does this saying even mean in the first place? That you shouldn't marry a woman who isn't a virgin? or has had multiple sex partners? Or just a woman who thoroughly enjoys sex?
It almost comes across as if you're expected to just fuck around with super horny/kinky women until you're finally ready to settle for someone who you're not as sexually compatible with. But if you love fucking these 'hoes' so much, why would you want to marry someone who perhaps isn't as sexually adventurous or doesn't enjoy sex as much?

It's entirely possible to find 'wife qualities' in a woman who has had previous partners, is kinky, super horny etc. And I'm not even going to begin to get into the irony of expecting sexual purity from your partner when you've been hoeing around yourself (or desired to), I'm more so wondering if these guys are actually aiming to compromise on sexual compatibility for the sake of purity.
