What is this red bump on my penis?
A couple of days ago I went to baseball practice without any worries about anything. I had gone to the bathroom many times before I left and I hadn't spotted anything. When I came home I took a shower maybe an hour after being there and while I was cleaning my penis I had noticed this red bump on the lower part of my shaft. It was surrounded by hairs so I tried to pop it but it only made it worse. It then seemed to get red and swollen. It looked like it had gotten bigger. My ex girlfriend and I were about to have sex at one time. This being my first time, but I just didn't feel right and as I came in contact with her I pulled her off and said I wasn't ready. I can't remember very well if it was her first time as well because before we dated I had heard rumors that she had been fingered by someone wand had possibly had sex. I had asked her before hand if she was clean and she said because of the rumors her mother had her tested and she said she was fine. I know other guys who have and sex with her and who seem okay. So I don't know if this is an STD or not but I'm hoping it isn't. Oh and yesterday I was able to squeeze it and blood with a mixture of clear fluid came out. I squeezed some more but I got the same result and then after a while it seemed only blood came out. So I don't know what this could be.
