>>11130239It's evident that 14yo boys, 21yo guys, 31yo men and 51year old men all love to look at 21yo naked women. Women are grown out between 16 and 18, then have most fertile years from around 18 to 23 after which it steadily declines. After 31, deficits in born babies start to be much more likely - a 33yo childless women has good natural reason to be nervous. Getting babies between 18 and 23 is biologically smarter, you're the fittest for birth around that time. At 45, you're effectively out of the baby game entirely. If you don't have already and want offspring, there's no point in mating a 45 year old.
For me, health is less important and there's no border at 45. A 18yo will want to data a guy in their 20's but it's common for a 18yo to find a gray haired 40yo guy sexy too.
Nevertheless, men health also declines after 20. Like with women, a 18-23yo will be physically healthier than any older age, statistically. This is also where e.g. testosterone production peaks. After 30, a man (and a women) can start to notice skin irritations that won't go away and small but chronic muscle/joint and bone pains emerge. A 36yo football/basketball star can't compete with his 23yo self when it comes to endurance.
Stangely, however, with humans, we can run longer at steady pace in our 30's than in our 20's, but that's really an anomaly. With sprints, a 23yo will always win over a 36yo assuming the same training/knowledge/condiction.
So yes, males any age want to fuck the same 21yo (porn star age. A 33+yo in porn is mommy fetish territory). Meanwhile, a mid 30-40 man is usually at the peak of his career and still interested in fucking around.
