i am a 20yr old boy,6ft tall and weigh 80 kgs.i have the problem of man boobs since last 5 yrs,i thought it will go away with age but it didn't,i am very embarrassed with the condition,my nipples are also very big and sensitive to water and touch ,i don't do drugs neither smoke or drink and have a good diet too.i don't have much facial or chest hair,only some in my chin region,though i get good erections.
i am very worried about the condition,please let me know about the possible causes and cures.
