Hello all. I have a bump on shaft of penis. Ive had it for about 3 months now, I originally thought it was just a pimple, from sweating, heat, etc. But it seems to be getting larger and not forming head. It feels hard and lumpy. When I do try to 'pop' it white smegma like substance seeps thru pores, and has cheesy smell.( I am circumcised though). I went doctor and he seems to think it's herpes and am awaiting test results , though I really dont think it's that. Since ive tried to repeated pop it, is now larger and has a yellowish milky discharge. Seems very similar to ingrown hair or infected pimple. Any advice?
