Small hpv like bumps on the shaft of my penis, had even prior to sexual activity. just barely off skin color. smaller when erect. any idea? i am 16

Probably not..., but: I assumed you're 16 and virgin. If so, the described lesions may likely be small moles, and its visible relative size may look varying resulting from skin stretch at erection and comparison to the engorged erect penis. So, if they don't hurt you and have no change in their number and configuration, leave them alone. If still in doubt, see expert timely. But ultimate determination relies on biopsy.
