Hi, I did a circumcision when i was 11. Now i am 23.I want to know if I am having a concealed one.When flaccid, it is very small. But when erect, it is around 5 inches. Also, if I pull the shaft, it is actually longer as the skin appears folded when not pulled. This is causing me mental problems. Please guide me. I weigh 175 lbs and am 175 cm tall. Could this be rectified by surgery?
