Can you go into more details on your SO's stance? There's some info missing IMO. promiscuity => healthy state of mind or life about sex => healthy don't seem like the actual arguments.
Yeah, not calling out something as "bad" implicitly condones it. Promiscuity is interesting in that it can't be "conquered" the same way drug/gambling/etc... are. The "brokenness" hangs over someone even if they "reform" since socially there's no full-redemption narrative.
