Hi, it's not something new, but i just can't figure out what it is.it happens after i watch porn (no action taken), and afterwards when i go pissing, i see 1-2 very small pieces of yellow "sesame" on the tip (inner foreskin) of my penis. i can piss them out or take them out with tissue.it doesn't do anything, no pain or whatever. but i just want to know what it is. anybody know?
