Females and males have different underwear to reflect the differences in anatomy. Most men's briefs allow a little more room in front to accommodate a penis and testicles, whereas women, who do not have either, need a little more room for wider hips on the sides of their underwear. Underwear OS one of the only pieces of clothing that is VERY gender specific (other than dresses, I can't think of any piece of clothing that either only men or women wear exclusively) only because they are design for very specific pieces of the body!

do males and females have different abilities when eatimating size
The males are called males and the females are called females. SIMPLE!
Very very small
Yes, males typically have XY chromosomes and females typically have XX chromosomes.
i think they do
The cost of reproduction is different for males and females because they have different biological roles in reproduction. Females invest more energy and resources in producing eggs and carrying offspring, while males typically invest less in producing sperm. This difference in investment leads to different costs associated with reproduction for males and females.
Because males are more musculer
The word "underwear" can mean the undergarment of either males or females. The word "panties" means only the undergarment of a female. Although some males do wear panties, as they are sooooo comfortable compared to mens undies
Females have different physiological needs than males. Females have a system where they conceive, gestate and lactate for their young, whereas males are simply focused on mating with the females. Males tend to be more muscular and larger than females, but not less "frail" than females.
Talent?
yes
Pretty much the same that's different between males and females of any mammal specie.
