Okay so out of nowhere I noticed a bb sized lump on my penis.....its not on the outter of my penis so its definetly not a STD..... its like its on the corpus(the inside of my body) when flaccid its harder to find but i can find it its near my testicles kinda deep and can be grabbed and moved a little(very little movement), when erect its more noticeable and doesnt move as much....... for example if it my dick was up and against my belly button it would be on the udnerside near the bottom close to testicles on the bottom left side....anyone know what this can be? kinda worried and dont got no health insurance or money for a doctor right now so its outta the question......kinda showed uo outta nowhere...from what I read though cancer in that area is more likely to be on the outside of the penis/skin...
