Hey man!! Open up..
Open up yourself. You don't need to hide your emotions just because your gender is male.
Crying is not a girly thing. If so was, then half of the population would have the tears only. When your eyes also have the same looking, same feeling tears then why do you always try to hide it?? Its neither illegal, nor makes your that equipment down there vanish or inactivated. Crying shall not make you less than anyone else.
Well, I know it's hard for you because you have grown hearing this, "Don't cry like girls!!". Okay, at least cry like boys. your pain is not gonna be less if you keep worrying about your 'manhood'. And if someone says you this again, "Hey, stop crying like girls!", just get rid of them. You are not a machine, you too have emotions and emotion burst out. The only thing you need to do is opening up yourself and be the way you are..
