Who cares about a broke guy who is good in bed? You said it yourself that rich people rate their life on a time well spent. A loaded dude can pay for sex not just because he can't have it free, but just because he's rich.
We are in an era where even love is measured by the number of gifts one receives. So obviously a marriage cannot just survive on good sex.
Well good sex is great,but food is more important.
Living in a place that is fairly safe is important.
So good sex and some money should work out fine.
1)Sex is complex in long term relationships married or not married (long term = 10+ years)
2) Good sex is one part needed
3)some money is another part needed
4)Love or like or attraction is needed.
5) Luck is important.
so you can have it all and get covid 19 die and the marriage is ended.
My wife and I both had covid-19 we were sick for a long time.
Both of us did not give a fuck about sex we wanted to get healthy over all other things.
We healed and back to a nicer life.
and we are back to having the things needed to be happy.
