Hello. While I am erect and masturbating I can feel a small gristle-like spot or lump or dot thing on the shaft of my penis. It is not painful at all but when masturbating it is uncomfortable and of course not pleasurable. I can masturbate but I know it is there which is somewhat off-putting. It is rather difficult to find while flaccid and it is under the skin, but due to the erection it appears to move down my shaft. I don t know if it is a hard gristle bump or if it is a sort of spot. I can t squeeze it because that would mean pinching my skin which would hurt a lot! I have had a look elsewhere online and I don t think it is a fordyce spot; it could be a lymphocele but it is apparently always present; it is not lichen planus; it is not genital warts; it is not a herpes or syphilis type of sores or ulcer and again it s not painful but is a bit uncomfortable while masturbating; I thought it could be peyronie’s disease but reading more about that, that is not causing my penis to curve; it is not molluscum contagiosum; and it doesn t seem like cancer of the penis and I am not worried about that, plus I am way younger than 60. So I am not certain what it could be. I have noticed it only recently - I d say in the last couple of weeks or so. I do have a masturbation toy which you can have sex with, but it is not well-designed, no matter what they try and advertise falsely, because it has become rather loose. Sorry to be graphic. Other than that, I am at a loss. Thanks.
