I have had fordyce's spots on my penis and testicles for quite a while, but recently i have noticed 2 spots on my penis shaft, one on the top side and one on the bottom side. They both seem to be getting larger and the one on the bottom side of my penis is getting quite large and is starting to get slightly painful and has started to go red. they both look like pus filled spots because they are both white. the one on the bottomside of my penis is starting to irrite me and is slightly effecting my sexual life. I am slightly worried about them as i dont know what has caused them. What do you think could have caused them and what do you think they are? I dont know what to do about them and i am getting quite worried about them. What should i do?
