Around 2013, Rollo Tomassi put out his infamous SMV chart that where he asserts that men's absolute peak was 36 (let's say roughly 35-40) and women's peak was 23 (let's say roughly 20-25).
I disagree about the point where men peak in life. I think men peak around 25-30. The reason for this is that it is difficult to pull off larger age gaps in extended relationships. A 27 year old man has a good chance of seducing and retaining a 22 year old for the longer term. That's a normal and societally acceptable age difference. A 40 year old man is going to have a lot of challenges with seducing and maintaining relationships with 21-25 year old women, even better than average 40 year old men.
There's a reason why the typical 30s/40s man is a thirsty man who ends up settling for some mediocre to subpar woman close to his own age. That's not a man's true peak.
I think the 50th percentile guy at 27 is better positioned than the 50th percentile guy in his early 40s.
A lot of younger men (this is true of both
@Barrister and myself) have to spend a good portion of younger adulthood de-programming from blue pill beta male conditioning that came from mothers, sometimes fathers, the grandparents' generation, and K-12 school teachers who are mainly female. This can take a while and some men truly never de-program from the blue pill, AFC, beta male ways.
