Hey I had this cyst looking size pimple on the left side of my penis shaft .. It was big at first I Poped most of it out like a pimple.. Then there was a black hole in the middle and white around the corner , which convinced me it was a cyst. Later on I took a needle to it, to kinda open it more incase it was a cyst to let all the guck out. It s now pretty much gone, but it s sorta pink around it, and in the middle looks light light white. I have pictures if need !
