I don't get why people have this odd notion that boys don't cry

I don't get why people have this odd notion that boys don't cry no matter how much pain they're suffering with inside.
If that's the criteria for boys I don't think I want to be called one because humans cry, get emotional and get carried away by some or the other things.
Yeah I am a boy and masculinity doesn't ever followed stony hearted but only slight greater in muscular power thats how we are created.
And let me be clear, I am a boy and I am much more emotional than any other girl. I can never see anyone in pain and end up crying on their situation. I get panic for a little things not because I am a coward but 'cause I care a lot about those little things. I feel blessed when anyone share their day-to-day talks with me. I don't know how to deny anyone asking for help.
That's how I am. Not at all,like your definition of a guy 'must be like'.
I am human and I am proud of every tear that I shed and for being blessed with heart which feels connected so much, for this world is too harsh for people who doesn't feel anything but lives anyway.
