I have tiny bumps on my penis that I though were herpes. I got tested and all tests came back negative, blood test and swab. It s seems after I masterbate more bumps arise and after a couple of days go away. What could this be? Also my lymph nodes in my groin are swollen.
Thanks for asking in Chat Doctor forum If you are having swollen lymph nodes in inguinal region, then it is suggestive of infective/inflammatory lesion over there or from Chat Doctor.  So, please visit dermatologist for further investigation & recurrence. Meanwhile, use protection while having sex. Masturbation is not related to this. All the best.
