> Okcupid’s data scientist cofounder did a bunch of research on this and confirms your assertion

said assertion:

> women's sexual value is at a peak very early (let's say 18) but a man's sexual value peaks later (at least 30+)...sexual invisibility many men feel as teenagers...

OKcupid data scientist cofounder says in that article:

> Women generally like a guy to be the same age as them up until the guys hit about 40. But when you flip it around, when you look at how men perceive women, it's pretty much a just straight ticket vote for 20, which is the lowest age I looked at in my data set

So young men aren't invisible according to this data. And:

> This is just measuring people's opinions, not what they actually go out and do. What you see when you actually look at what people do, you see the realism set in. So these 40-year-old guys ... they people they actually have the courage to actually go out and message are a lot older: it's 30, 35-year-old women

So stated value is 20, but in actual practice women older than this are also doing just fine.

In practice though, 15–30 year-old single women get much more romantic attention than e.g. 45–60 year-old single women do. Some older women miss the kind of attention they used to get when they were younger (while some are indifferent, and some are relieved).

Many young men feel rejected/alienated. By age 35 or 40 men have often figured their life out (figured out what they want, found a partner, become more effective at approaching people, whatever).

I haven’t heard any men in their 30s or 40s mention that they aren’t being chased around by eager suitors the way they used to be. And I haven’t heard any women in their 20s complain that they can’t get a date however hard they try.

OkCupid is one of those dating sites that have a high bar to entry (you need to invest a lot of time in just creating your profile), so that people who are there are looking for serious relationships.

If you did the same analysis for Tinder you would probably see that guys 35+ do message girls under 21 years old A LOT, but that isn't meant to last, both sides are typically just looking for casual sex.

Good news is that one of the OKCupid cofounders (the one who wrote those original data science blog posts) ended up writing a great book called Dataclysm[0] that expands on top of that earlier research + tons of completely unrelated and interesting research and analysis. It is really well written, the writer definitely has his way with words, and his analysis is very careful and reasonable. I heavily recommend.

Back to the original point I was trying to make, in the chapter of the book on that topic (as opposed to his earlier data science blog posts), he uses not only OKCupid data, but Tinder and other dating apps as well. I remember there were a few small outliers, but in general that trend from the original data science blog posts still stands. Oh, and he also explicitly compares his old analysis vs. his present one. Definitely an interesting topic, and the book, luckily, applies similar rigor to a bunch of other topics completely unrelated to dating dynamics.

Most important, many women start off with little urgency to have children, but at some point in time it becomes clear that their fertility span is limited. Then they feel a tremendous feeling of urgency and often aren't happy with their prospects.
