Do guys learn about periods?!

guys learn from their mothers, sisters, etc. at least most do. they only laugh because their less intelligent friends do this.

They should, even if they don't learn it in school they will learn it in life later on when they get a gf and she is on her period.

They learn from there mum or sister or when they have a girlfriend or when they know about sex.
They all learn at some point don't worry.

Yes, they definetly are aware that girls have their periods.
