Oh what am I asking. Answering that wouldn't be politically correct.
I honestly don't know what you want here in terms of a "perfect masculine specimen". Is it an ultra manly man in looks, behavior, or biology? A man who is super straight and has sex with a lot of women, like Mick Jagger or that basketball player whose name I just forgot? An Olympic weight lifter with extra chromosomes? A man with a super high sperm count? A man with an extra testicle?
Or a statistically average
human male earthling: straight, Chinese, 5'9" tall, flat feet, aged 37, 2-yr college graduate, lower middle income, married 10 years with 1 child aged 8, no prison record, two unpaid parking tickets, leans Buddhist, smoker, does tai chi, likes Celine Dion, has a slight gambling addiction?
Gay men are, worldwide statistically
in the minority, is that your point? So are handsome men, tall men, short men, atheist men, fat men, intelligent men and stupid men. Albino men, very black-skinned men and billionaires are also in the minority.
Again, what is the point you are trying to make?
