Why do girls have periods and all the gross things but guys only have hair growth and testicles?

one awnser-puberty is cruel to females. Or you can believe that girls need periods to (A) tell if they are pregnant or(B) just sigh that they are healthy. You produce body oils too, and i don't know the answer to that one. but also itas because were girls and there guys so yea and also because they dobt have to have babies we do!!! there the one to make it

and without periods u wouldn't be here asking this question... so u need 2 to make it work so u need a boy and agurl to make a baby soo yea... and imagine if both had periods?? how would u make a baby with that???

Guys cant put tampons in there pinus

you spelled penis wrong u retard!!

They get wet dreams you wasteman.
