I have a crapload of concerns/questions that i need to know the answers to! At what age does the penis stop growing? I'm 16 and im around 6.5" but I do not look like an adult yet should i expect another growth spurt? My flaccid penis is actually quite small and there is a vein that is curled up on the left side and forms a bump. Is this normal? Finally when my gf and I get intimate i cannot keep an erection! I have an N-curve and my scrotum seems to be too big almost. It is really frustrating that i cannot keep an erection what could be the cause? I want to go to a doctor but what shoudl i say?
