Possible "Growth Spurt"?
 

I'm pretty scared. Terrified, actually. Over the past few weeks I've noticed my penis has been looking bigger than normal. It's still far from average but I'm afraid itll keep going. I've never measured it before, so I'm not sure I could tell if it really is growing. Is it even possible? Is there a way to stop it? I love the fact that when I get real swoll my cock is no bigger than a oat. I don't want this to end.:(

I know that when a lot of guys try to get bigger they use pumps that make a vaccuum around their penis...so perhaps you could use the same principle and pump air into the chamber around your penis to force it to be smaller

though there is the concern of air in the urethra, you could probably dip the tip of your glans in warm wax or something to seal it to keep air from bubbling in

You should probably form the wax into a longer shape and slip it into your urethra just to make sure it's plugged, you really don't want to be pumping air into there.
