If men are more interested in porn and VR type stuff, they don't sound like they would be good relationship partners and it's likely best they are out of the marriage pool. They're still getting their needs met and the sex workers are getting paid, so seems like it's for the best all around.
I tend to agree. At least individually I do. But for society in general, I have reservations about this. Frankly, we don't know if they would be good relationship partners or not, some would, some wouldn't. And yes, it's good that the "bad ones" are weeded out, but I'd put forth that lots of "good ones" weed themselves out too. In some ways, I think that you might wind up with a situation where more "good ones" are weeded out than bad. Similar to an A, if men who aren't "good with women" remove themselves from the dating pool, well, you'll be left with a group of guys are are very good with women; IE, "smooth talkers", "players", etc. The men who have "trouble" (who, in my experience, while less desirable as partners, seem to be much better husbands) with women are the very men who will "opt out". No, not in droves, at least not initially. All of this happens at the margins, but it's already happening with the "herbivore men" in some counties. And marriage/birth stats are showing a very clear trend away from both. Who knows, perhaps that's a good thing, more individual autonomy and fewer concerns about overpopulation and the death of the planet from man made problems. But it's a shift, for sure, from what we had for, well, just about all of recorded history.
Getting regular sex is not a substitute for a real relationship.
For some, you're correct. For others, less so. But you don't even need to go as far as "regular sex" to see that there are potential problems here. How many threads are there about husbands "preferring porn" to sleeping with their wives? And that's not even sex, and it's still "rewarding enough" to get some to withdraw from a real relationship. Thing is, it doesn't take a dramatic change to have a dramatic impact. If 10% of men "dropped out" it would have a drastic impact to the dating/marriage market. And the research on this is really clear, when there are more men then women, relationships tend to move quickly to marriage/children. When there are more women than men, relationships tend to become more ephemeral and short term.
It's going to be interesting. Not my problem, this is something the next generation will get to figure out for themselves. And I'm sure they will, but just not sure what that will look like.
