mens peaks are generally much longer than womens too
Personally I think men have two peaks, one at university i.e. 18-24 years, where they probably hit their peak physical shape and have grown out of their teenage appearance. But then from 35-45 years we develop a more mature manliness which I think many women find appealing. Although physical shape goes down, ruggedness and maturity goes up and this also has appeal. Think Don Draper, Clooney etc.
Between 25-35yrs is just an awkward stage where you're transitioning between the two.
Woman are in their prime from like 18-25. Men are in their prime from 24-35.
Everybody hits their peak at different times.
Nigella Lawson looked better after 40 than she did in her 20s.
Kym Marsh is another who is getting better with age.
Kelly Brook is another.
Generally though, 18-21 for me.
Rolf Harris' everywhere ffs
