32 5'8" 168. I have over the past week noticed in several places the appearance of small bumps on my penis shaft. they are not clustered rather they are separated by several centimeters. they are on the side or bottom of my penis shaft. I masturbate daily and tend to take a while when i do it and have to go fast to achieve results. i also sweat a lot. my sexual partner recently was tested and came back clean on everything. the bumps apear with a redish tint to them and if I squeeze them a little blood comes out and a scab is able to be peeled off.
