So ever since I had a one night stand I've had this itching sensation on the side of my penis shaft and around the rim of my penis head. Tested negative for herpies 1 and 2 at 4.5 months and at 6 months. Both tests were igg tests . I have tried 4 different creams that I got from my urologist and dermatologist. The creams make the itching stop but it never goes away. My lymph nodes in my groin get tender sometimes. None of my doctors think it's herpes but idk what else to do. The itching comes and goes, some days worse than others but never goes away completely! Any ideas what it is?
