Lord ram is the icon of Indian manliness. He was the king of ayodhya. You can learn about him in ramayana which is an Indian epic. He lived his entire life for others. He sacrificed his youth for his father's
Then he sacrificed his joy of fatherhood and his marital life for the sake of happiness of his subjects. His subjects thought his wife is of loose character because she was abducted by the demon king ravana. So rama send her (then pregnant) to the forest.
In this way rama sacrificed those pleasures which a man values most for the sake of others. This is the value which most of Indian men praise till today.
Indian man lives for others not for self. For that sort of living Is very narrow and distasteful. This is the essence of Indian art of manliness in a nutshell.
there are a second side of lord rama too. the side of brevery and valor. he fought many battles with the demons and monkey-men which might entertain the warmonger western mind. he killed many demons who tortured men particularly sages etc.
he fought the greatest battle on earth against demon king ravana who abducted sita, his wife. you can read those stories in ramayana too.
