What's wrong with my testicular sac? (WAYYYY TMI)

[TommyTutone]

First off, yes, I should see a doctor, but before I freak out I wanted to see if I was the only one like this (perhaps this is better off for IMHO?). Second, I would probably be up for a Darwin award based on what I'm about to type, but please just not too harshly.

For the second time in my life, I noticed a small lump under the skin of my testicular sac (is that even the right term)? It did not hurt to the touch, but of course has me concerned. I would feel it now and then, and although it did not get bigger, it did not go away either. The lump was very solid and measured probably no bigger than 3 mm.

Curiosity got the better of me last night, after having this one for about a month, so last night I took a small knife, and after pinching off the skin around it, cut the skin away, exposing the lump. The lump appeared to be at the base of the skin, but not at all attached to the testicles themselves. Using some freshly sterilized nail clippers, I then tried to excise the lump. There was a very small amount of blood around the lump from where I had removed the skin, but not from the lump itself.

While I could not 'remove' the lump per se, I somehow punctured into it near the base. What came out was neither blood, nor pus, but more of a thick white fluid that had the same viscosity and thickness of perhaps bathroom caulk as it comes out of a gun. The area where the skin was removed is now a little sore, but I applied antiseptic and a bandage.

Now that I have thoroughly disgusted all but the mightiest among you, does anyone have any idea if this is normal (the lump, not my treatment of it), or should I start considering chemo or having my balls removed?
