what is this on my penis/foreskin? should i be worried?

thats a fungal skin issue yeast most likely

Jimmy, how long has your skin been like this? Are you sexually active?

its only been this way for the past day or two… i am not sexually active

What Kim says is the most likely thing you have. You need to check on your personal hygiene, regular showers, daily if you can, fresh laundered underwear each day, that kind of stuff …
