The process of sexual reproduction requires a male and female to mix their DNA and produce offspring, as per human nature. The penis is a delivery device for the males' genetic traits (sperm) to the female ovary (the egg) via the vagina, or the receptor. This is the nature of all sexually reproducing species.
A vagina is a female reproductive organ. It id developed to accommodate the female cycles and childbirth. However if a person is born as a Hermaphrodite, that person most likely has both sex organs, but one of them is developed more than the other. In summation, boys do not have a vagina because, the vagina does not perform the biological functions that a male's reproductive system would need.
