Is it cancer???

On Wednesday night/Thursday morning I was talking with my boyfriend on Skype, we finally had time to talk more than twenty minutes so it got us really happy. I finally believed him that he's working for the polish government (after being interrupted by phone calls every two minutes) and realized that it all isn't a fairy tale after all.
well, we started fooling around online and he really turned me on.
I started touching myself, getting ready for some online fun when I realized that I have some kind of a bump on my right testicle, I got turned off momentarily, I told him to hold on for a second and I started inspecting my right nut.
Yes, it was there, a lump about 0.3cm in diameter, it was pretty hard in touch and kind of big.
At that moment I got a flashback from "Queer as Folk" when Brian Kinney finds out he has a testicular cancer, it got me really freaked out.
I couldn't fall asleep for the rest of the night, thinking... "What if it's cancer?"
I don't know
I'm kind of o.k. with it today, because I realize that it's not the end of the world and I don't even know for sure what it is, so I'm about to shchedule my appointment with my family doctor on Monday and if it's possible with Urologyst on Wednesday, so I'll find out for sure.
What I know for now is that even if my testicle is going to be removed;
a) I can still have kids with one testicle if I somehow turn out to be straight ( impossible I'd say)
b) It's not going to affect my sex life
c) I get a fake testicle in the place of the one that had to be removed, and I get to choose the size of it :) lol
Maybe i should let them remove both of them and get big, fake cojones? that would be kind of hot...

But seriously, I'm still little bit affraid of going to the doctor and God, I just hope he's not gonna examinate my prostate "just in case"
I don't want anybody to stick their fingers up my ass without my permission...

P.S. I checked today, and the bump is still there.... does anybody think it might go away by itself???
