Dear Dr, I masturbate quite regularly and I am 16 years old, I have done it for a couple of years. Recently I have been getting chest pains, not that painful but mildly sharp, also recently I get random testicle aches however I have checked and I have no lumps and the testes aren t soft, they still have hard foundations, should I be worried that I have cancer or any serious illness? I am characteristically paranoid about things quite often, I just want to know if I am well
