First off, a "real man" has to exist. Males are all horny 17 year old boys.
But if there was a "real man" he wouldn't be afraid of his emotions. He wouldn't be afraid to cry. he would be strong when needed and sensitive when needed. He would be the type to take care of his family, and be responsible for his actions. He would be honest. He would be trustworthy. And above all he would be authentic to himself.
But since no man like that exists, we're all stuck with nothing but horny 17 year old boys.
