Yeah, prior to the resurgence of PC in the late 10s, The Huffington Post was giving airtime to what we'd today label Red Pill Knowledge

Quote: "Hooking up with some guy in a hot tub on a rooftop is fine for the ladies of Jersey Shore -- but they're not trying to get married. You are. Which means, unfortunately, that if you're having sex outside committed relationships, you will have to stop. Why? Because past a certain age, casual sex is like recreational heroin -- it doesn't stay recreational for long.
That's due in part to this thing called oxytocin -- a bonding hormone that is released when a woman a) nurses her baby and b) has an orgasm -- that will totally mess up your casual-sex game. It's why you can be f**k-buddying with some dude who isn't even all that great and the next thing you know, you're totally strung out on him. And you have no idea how it happened. Oxytocin, that's how it happened. And since nature can't discriminate between marriage material and Charlie Sheen, you're going to have to start being way more selective than you are right now"
On the male end, we encounter findings such as those reported in the second link I provided

"To shed further light on these issues, I recently completed a research study that involved in-depth interviews with dozens of men who had engaged in regular casual sex to understand the impact on mental health and emotional well-being. These interviews revealed a complex picture.
To be sure, many men reported hedonistic enjoyment of casual sex. However a large number of men also reported that a promiscuous lifestyle was damaging to their mental health, and many felt better after ceasing such activity, as evidenced in the words of a study participant:
"The reason I stopped essentially is because I met this girl I really liked, and I was really like ‘oh, why am I doing this?’ There’s no purpose and I’m just like draining a part of my soul. Because, each, each girl you meet and have sex with, it’s like if you’re giving her part of your soul. And, at some point it’s like if you broke your soul into like, a lot of fragments and you’re giving it away and you like feel empty because you’re not, you don’t have this special relationship with anyone."
Notably, the concept of the "soul" was used by several other study participants, who similarly stated that causal sex "damaged their soul." Moreover, some noted that promiscuity could feel almost dangerously addictive, interfering with important functional activities such as employment and education. This is witnessed in the words of another study participant:
"I was totally addicted. It was soul-eating. I discovered I was addicted about 3 or 4 years in, and I realized that my life was taking a drastic turn. I was in school but I wasn’t interested in school anymore. I was heavily into running but I wasn’t interested in a single bit of running. I was just interested in clubs and girls… and I was tired of just focusing on girls and not focusing on my life… I decided to build myself first, that is what I am doing now…"
Another concept that emerged from the study was "emptiness," with participants reflecting that regular casual sex led to an existential emptiness. Again, this was an unpleasant subjective experience, prompting some men to change their lifestyle, as stated by another participant below:
"I just wanted to f**k as many women as I can, but I could feel like its empty... during one week, I was with 4 or 5 different girls but the next day I felt this emptiness, and I would say each of them take a part of your soul, and make you more empty… because of that I stopped doing that… and I knew this was a mentally healthy thing to do."
In a free society, it is a fundamental right to enjoy a sexual lifestyle of one’s own choosing (within the limits of the law). As the pandemic has abated, more people are looking to rekindle their sex lives, including casual sex, one-night stands, and "friends with benefits." For some people, this will be harmless fun and an enjoyable recreational activity. But some research—including results from my own aforementioned study—indicates that a promiscuous lifestyle can be detrimental to mental health. Casual sex can have a damaging dark side and may come at a psychological cost. This should give pause for thought"
