I have a horse farm and we do AI work and live breeding :). So lots of sex and birthing happens in my "realm" of the universe.
I don't have kids, but I have been there in the birthing process "a bit".
The thing I try to share/show is guys are truly scared and live in fear when it comes to true intimacy (even me).
It is even worse if a heterosexual couple has very little communication and conversation time.
This is why my silver lining view of being a demisexual type of person benefits, because there is a bunch of talking before any intimacy happens.
If a woman desires (if I was single) a quickie, it won't happen with me. YMMV of course with other guys ...
