a few yrs back a dated a lady. we had a short sexual relationship. after we seperated i noticed 3 bumps on the shaft of my penis. they didnt hurt at all and they went away after a few days.fast foward to now and i noticed 2 bumps on my crouch area. one on the right and one one the left. the white tipped one looks like a pimple of sorts. i once busted one and puss and blood oozed out. i thought i had foccilitis and i bought some tetrasil. it makes the bumps go away but after awhile they resurface.could you please tell me what theses bumps may be?
