You are not owed sex or intimacy. To men: want to be desired by other people? make yourself more desirable. As for women in this situation, that is largely self imposed because their sex drives are lower and they are often in denial about how their attractiveness declines with age, and are unable to adjust their expectations to match.

In the modern dating / hookup culture young men and older women are the clear losers. Men are figuring this out and largely either going full anti-women "red pill rage" into "$!tches aint shit" using women when they're older or opting out all together. Women party it up when young, and are then shocked only when the "good times" start to end as younger ladies supplant them.

The age old solution throughout the ages, has been to control female sexuality with shame (often enforced by other women). This is now considered unthinkable, despite the surge in single parent homes, massive decline in birth rates, increased loneliness and decreased happiness by all. So instead sex bots, prostitution, more welfare, and artificial wombs are promoted as the only politically tenable out. I think the future shall be inherited by the Amish, Mormons, and other such groups that have managed to find ways to maintain family units in opposition to modern culture. They're certainly the only ones breeding at above replacement levels.

TLDR: in practice based religion beats out free love in providing more sex, without all the messy fatherlessness and STD problems to boot.
