The issue with promiscuous men wanting non-promiscuous women is about his hypocrisy around pious conservative values
For the most part, non-government related conservative values originated from religious principles. Most of the cultural and interpersonal virtues of conservatism have been adopted from religious doctrine.
I say that to say, being “culturally conservative” and being aligned with :: insert your preferred religion:: is more or less samesies. If that’s your jam, then one should be reminded that conservative religions tend to emphasize sexual piety and discipline for both genders. For example, in Islam, a husband with multiple wives only happens under strict guidelines, and was historically typically only smiled upon when done as an act of altruistic community charity (e.g., a family takes on a widowed woman in their village).
So when certain men pump-fake about being of “conservative values,” but then make statements like “it doesn’t matter that I’ve been promiscuous/continue to be promiscuous, I want an unsullied woman,” then yeah, their alleged conservative virtues read as self-serving perverse bullshit.
Inb4: If you’re not a culturally conservative promiscuous man who doesn’t pretend he has consistent values around sexual discipline, then this OP isn’t referencing you.
