Hi, so recently i noticed a pea size lump on the shaft of my penis. it is small shiny and bulgy kinda looking like inflated maybe pus. at first there was 1 but a day later another one popped up but not as bad as the first one. it first appeared after i masturbated. Im 16 and have never had sex. the lumps are directly under each other. the lump doesnt hurt or irritate unless i apply pressure or fiddle with the skin
