It would be hilarious if they branched out to "The Gal in..." or "The Dame in..."

Should have said "even later than early '20s".

It's pretty easily explained by typical physical maturation of male & female humans. Puberty happens later for men on average. They often don't develop full musculature until their early '20s + whether someone is a professional/working class, ability to support a family would occur at a higher age.

I watched that a couple days ago. More softcore directed by women, please!
