Hello over the last week i have noticed that my penis has grown, I guess you could say a decent amount, Im a 23 year old male, before my penis length erect was around 7inches and now it has grown up to 10 inches, i have went to two different doctors both said there was no fluid build up, or anything wrong woth it so is this just a new penis growth spurt i havent heard of or do i need to be concerned.
