Maybe we should stop assuming that buying a home or getting married are huge contributors to sex.

And then just ask.

Don't ask them if they want to pursue your expectations. Ask them what they want.

And if you ask young Japanese women, they respond that economic factors, such as the cost of raising a child, work–family conflicts, and insufficient housing, are the most common reasons for not having as many children as desired. Maybe it is this simple/fundamental. :)

Yes, but that's answering why they don't have as many children, not why they aren't having sex.

It's also only asking women who already have one or more children.

It tells us nothing about why so many people are not having sex.

Still living in your parents’ house is something of a barrier to sex.
