Mild pain in right testicle after masturbation and sex often I get pain in pelvic and right lower back. Testicle Pain will increase while riding bike and passes humps. I have stones in both the kidneys and also varicocele in left testicles. I do masturbation 4 to 5 times a week. Recently I left masturbation for 10 days and pain was reduced. I had gone through scanning several times and notice stones in kidneys. Pain is because of stones or is Der any oder reason behind it please suggest me. One more thing pain is not continues. And is Der any limit for having sex like once day twice day? Will varicocele and sexually active causes fertility problem in future because am not married.
