Nahhh... there are more to it than just age.
if this guy have all sisters as siblings, he tends to be more gentle too. Hence more sensitive to the needs of female as well.
if the horoscope or Chinese Zodiac of this guy is of a softer nature. He can be just as caring or even more caring than some females.
even the upbringing of the guy, how the parents 'drill' values into him, matters too.
I have friends who have older hubby / boyfriend, instead of caring for the wife/gf, ended up hurting the wife/gf through all sorts of ways, emotionally and physically....
so nope. dont't agree.
