Uhh no it depends mostly on what your genes are but nowadays u can change the size bigger so it really depends
Big penises
Who says that they are? I am sure that Japanese boys' penises show just as much variation in length as do the penises of boys from other countries.
This is typical boy behaviour. They do this as it takes the spotlight of their own size. There are boys with small penises when flaccid that have large erect penises, and vice versa.
some boys do in some boys don't
Boys do not have a vagina because their biological sex determines that they have male reproductive anatomy, which includes a penis and testes. The vagina is a female reproductive organ found in individuals assigned female at birth.
