I have felt for a long time that Hefner’s vision for sex has been a downfall for women. The advantage pretty much goes to the guys in this one - free sex and if the woman gets pregnant she kills the baby. But ...I think most women are different in the long run - we have a nature that wants an enduring relationship with the right person and destroying your own child is something that many regret in retrospect.
Too many women gave up their leverage too easily. Too many women thought we are just like men...when actually God has assigned us a different role..and to me it’s a fabulous role - to give life to and raise the next generation.
I think women, in general, had happier lives when they married in their early 20’s.
The advantage goes to a small percentage of “player” guys. Joe Average gets ignored or worse through his twenties; eventually he either gives up or tries to import a wife from a third-world country.
You are presuming that men, by default, don’t want parenthood.
