One Testical Bigge Than The Other.

[Skill]

First of all you need to relax. Having one testicle bigger than the other is perfectly normal. If you don't notice or feel any difference in your testicles then it's fine. If you feel some kind of a lump that wasn't there before, that's when you need to go and get it checked out. The odds of you having cancer are very slim. Don't be worried. I'm sure you're just paranoid.
