I was recently masturbating and at the end, when I ejaculated, I felt a pain along the right side and near the base of the penis. I usually masturbate without any type of lotion. I can still masturbate, but when I do I feel a light pain in the lower right side of my penis, and if i try to bend the erect penis upwords i get an intensified pain at the right base of my penis, almost like a muscle pull. Will this heal on it's own?
