While masterbating i noticed that my two testicles are different. the left one is a little bigger than the right one and the right one is hanging lower a bit. i think that it's normal but not sure so what do you think?
Vlad don't worry about it. They are never exactly the same size or hang even. But if you want me to check them personally, then I will be more than happy to do so.
It is normal for the left testicle to hang lower than the right. I'm not sure about size differences -- mine seem about the same size. You should see your doctor if you are concerned, and also to learn about how to do a testicular self-exam. Doesn't matter how young or old you are, just like women need to examine their breasts for lumps, guys have to watch their testicles for them too. Even teens can get testicular cancer, and it is VERY curable when caught early, as I understand it. I'll bet you can find a how-to about T.S.E. online real easily. Blue skies, -Jeffrey
