Hello, recently i had a couple small blisters pop up on the shaft, and it popped due to sweat and work, i drive forklift so constantly moving that area, and a few more popped up. Just as those were popped and start healing, i had another small section with like 6 tiny clear blister bumps pops up on the other side. I have a couple partners and one a couple weeks ago i didnt use protection. No painful urination or anything, no blood when they pop just a clear fluid, left lymph node got slightly sore and swollen but other than that no other real symptoms. Could this just be overuse? Cause i masturbate quite frequently. I need to know if i should seek a clinics help
