Im a 23-year-old guy dealing with something unusual lately. My left testicle feels like it's vibrating, and occasionally the right one does too. It started happening the morning after I masturbated the night before. Plus, my left testicle seems a bit softer than the right one. My penis shakes sometimes as well. Its been like this for the past four days. Sometimes everything feels normal, and Im wondering if I should be worried or if this will sort itself out. Any ideas on what might be going on?

Sounds like you may be experiencing some testicular discomfort and changes in sensation. These symptoms could be due to various reasons such as muscle spasms, nerve irritation, or even underlying medical conditions. I recommend you to take Ibuprofen 400mg every 6 hours for pain relief and inflammation. Additionally, you can apply a cold pack to the affected area to help reduce any swelling or discomfort. If the symptoms persist or worsen, it is important to consult a doctor for further evaluation and management.
