i have these white lumps on my testicles and im worried that i have a disease, im too scared to tell my mom but i definitely want to see a doctor and i was just wondering if these things are normal. im 13 right now and my first one appeared when i was 12 i popped it and i thought it was just a pimple but then another one appeared and i popped it but after a couple months another one appeared so i just let them sit there and i have three now. what should i do?
