I think that thanks to television and computer technology, we're all exposed to sex in ways not possible in the past.
It's a one-way street. No interaction other than yourself and a towel.
You can find articles on sex.
Nice to have, I don't object to it, it's an add on, if you so will, to the real thing. Which yes, is in flesh. Nothing can beat that in my opinion.
That is why I am talking about us temporaries, which are blind to the fact that we ourselves had plenty of the factors mentioned. For us (I don't know about you, of course), we had it all. Many friends, many occasions where boys and girls would make their first experiences, adults who engaged, married, aunties who pinched you in the breast, to see if there is something growing and mocked you when it didn't, singles having to sweep the place because they were too slow in mating - again a benevolent form of mockery - and so on and so forth.
Present time: too much Screen-time for kids, lockdown for about two years, isolation and such are anything but helpful in mating freely, families drifting apart - yadda, yadda. I am reluctant to give any further details because it is family related (you understand).
