It might be a HPV-cause wart. Or not. If it only could be that easy to diagnose skin lesions based on photos - we wouldn't need those dermatologists at all!
It could be a scar from a healed ingrown hair or folliculitis, could be molluscum, could be a trimmer accident scar, could be something else.
If you are worried it may be HPV, you should show it to the doctor, preferably, a dermatologist, or a STI-specialist.
