The difference a single chromosome makes

No, it’s absurdly high standards.

No it's just consent.

You can't help who you are attracted to.

You cannot force yourself to feel desire where you don't.

It would be wrong and unethical to pretend to be interested in someone just to get laid.

It would be virtue-signaling to just date someone out of charity.

Define “plenty”. I’ve seen the dating app data, it’s a tiny minority

40% of relationships begin online, mostly on apps. That's expected to be 50% of all relationships by the end of the decade.

An overwhelming majority of men and women are getting laid (over 70% of adults regularly, over 80% semi-regularly).

The app data shows that most people are dating or having sex or in a relationship.

It’s barely most and it won’t be much longer. Male sexlessness tripled in 10 years.

It's less than that now. You're thinking of the studies that included the first two years of the pandemic.

Also, quality is better than quantity. Rates of rape are going down. Rates of people being pressured by their parents to date people they don't want are going down. This is a good thing. More encounters are consensual and enthusiastic (whether just a date or having sex).

51% will be married before 30. That percentage is also rapidly dropping, in the 60s it was 90%. In a few decades it will probably be close to 0

Your speculations and extrapolations are ridiculous and do not line up with the data or the trends.

Firstly, most people are married by age 30. An overwhelming majority of people are married by 40. And almost everyone by age 50 and 60.

I think you're also forgetting that living together out of wedlock has only been (somewhat) acceptable for one generation.

Some of those people who are in loving, committed relationships aren't interested in marriage but are staying together longer and reporting happiness.

Sure with a very small percentage of men lol

No, with most men. And most men still have at least seven different sexual partners within a lifetime, almost twice the average for women.

Only 2% of people will never date or have sex, and most of those are severe untreated agoraphobics or asexuals, most of whom are women.
