I am getting lumps on my balls and it's itching, I'm getting uncomfortable. I think it is staphylococcus but I have never had unprotected sex, what could be the cause and what should I do to treat it?

 
Lumps on the testes could be due to many causes and should never be ignored. In your case though, what you perceive as lumps on the testes may be lumps in the scrotum. You should get examined by your doctor to find out the cause of your problem. You should not self-diagnose yourself as suffering from Staphylococcal infection. If it is indeed Staphylococcal infection, you should get treated immediately. At any rate, Staphylococcal infection is not spread through sexual contact.
