The other day after going to the bathroom I noticed I had a lump on my penis with a black dot in the center of it. I just sorta said what ever and went about my days.
However a few weeks/months ( I don't know ) another one apeared and again I let it be although i was getting worried. And finally a few days this time after the last i got a much smaller one barely visable to the naked eye.
I'm not sexual active infact a virgin, but I do masterbate from time to time. I'm quite worried now even though i figure it can't be an STD.
Please help if you can.
