In order to reduce the swelling, you are going to need a counteraction. A firecracker works perfect, especially if inserted into your pee hole.
However, just having it at the tip of your pee hole will do nothing. It must be in there deeper. Take a chisel and a 16-pound sledge to make sure it is in there, and good. Remember - don't light the firecracker before hammering it in. Let us now be stupid.
Ah, but how are we going to light it, shoved all the way down there (if you did it right, the firecracker should be buried in there so deep, you will not be able to see it). This is where your blow torch comes into play.
Now, in order to see deep down in your pee hole while your are going after the firecracker with your blow torch, we are going to need a light source. Unless you were born with four hands (if so, skip this step), you will need a light source that can work on its own.
In order to do that, simply pour a gallon of gas all over your genitals. Light it with the blow torch, and you should be well on your way.
