Why so early? Easy... so I won't have kids so god damn early if things ever happend! I've already had 2 preggo scares that would scar a man for the rest of his life. Besides I could get sperm extracted by needle (yeouch, birth control in itself if I ever seriously considerd kids!) so it's not really a done deal type thing if the surgery can't be reversed.
And I'm 19 on the 17th, but in any case I've already discussed this with surgeons before, just looken for more to get seperate opinions and idea's on types of work.
