Yes they are. Men produce semen which contains sperm and prostate fluids. Sperm causes women to get pregnant, prostate fluid helps sperm live and makes it easier for them to move.
Women produce vaginal fluids, which makes the vagina have less friction, and helps sperm live longer until they get through the cervix.
Biologically, boys and girls have different reproductive anatomy and hormone levels, which can lead to physical and physiological differences. Additionally, societal and cultural norms can influence differences in behavior, interests, and perceived roles between boys and girls.
Because of their reproductive organs.
boys are different to girls but I think that the causes are similar
the boys and girls both did different things the boys did fighting and the girls probably did cooking and sewing
Because they are boys and they have different parts from girls
boys date different girls because they either like different girls every week or they want to play the field.......but mostly because they like different girls every week.
Both girls and boys grow hair!!
yes there is difftrent class for boys and girls
Because girls are not boys, or to put it scientifically, for the human reproductive system to work you need both male and female. If girls weren't girls the human race would die out.
The issue is that boys and girls can lie
In boys and girls, the bodies become developed. That is the reproductive systems become mature and capable of reproduction.
