The day after, I developed a red bump on the shaft of my penis. It was initially just
a red bump that looked
like a mosquito bite.
A few days went by and it did not change. I tried popping it but it would not pop. There was no fluid in it. I squeezed very hard until it ripped open a little bit and scabbed over but it did not have much fluid in it, just a dot or two. The scab went away in two days. It does not itch, it does not burn, it is not a blister, and it is a solitary bump.
