Hey, about 3 days ago i started to devlop this bump just below the penile shaft. I thought nothing of it thinking it was going to go away. But now it had started to hurt a bit, when i stand it is uncomfortable. It throbs abit and there is a very tiny hole and when i squeeze it white stuff and blood comes out. It is under the skin and it doesnt feel attached to anything down there. Also it is a little sore right above the pubic bone area. I have not had any sexual partners in awhile so i do not think it could be an STD.
