I feel a sore on the side of my penis head. Whenever I masturbate and touch just the side of the penis head. I feel a minor strain. I’m not sure if its a disease or not. This is right after I spent one night with a full erection due to wearing tight leather pants and watching 5 hours of pornography. When i urinate I don’t feel anything. Also I don’t feel anything when i only touch my shaft.
