Dear doctor,
Recently during masturbation, I noticed a tiny bump on the shaft of my penis. I first noticed it 8 days ago. It is less than 1 mm in size, slightly lighter color than the skin color if I stretch the skin. In fact, I have to stretch the skin in order for it to become noticeable. There is no irritation, no itchiness, no discharge, or pain of any sort. It hasn't grown in size in 8 days, that was the first time I noticed the bump. I have been checking it for eight days, its conditions hasn't changed. Just because I was looking at the shaft of my penis daily, I also noticed a extra small piece of skin in the middle of the frenulum. It's about 1 mm in size. It's at the area where there is lots of rubbing from the underwear. It's soft, moist(doesn't mean wet or have any discharge), just not hard or dry, in fact, I have to wiggle it to make it stand out. It could have been there for a while, I m not sure.

My sexual background. I have had about 7 girlfriends in the past 16 years. The only one I engaged in unprotected sex was six years ago. I have been tested for STD last year, all negative.
Just wondering what that tiny bump is, also the extra piece of skin. Can it be HPV? I read that vinegar can help detect genital warts, is that true? Please help
