Buddy,
got the same thing, for a while I thought it was ppp (forgot what ppp stands for)... But it wansnt, because I later found out ppp was only around the head of the penis.
So, they are on the shaft? I would assume youre not circumsized. If you are, then they are found below the cut. Anyhoo, no worries bro, they're called 'sabacleous' glands (spelling is wong, no clue how the spell it) and hair follicles. They arent pritty, but they are natural, and if a gal has issues with it, she isnt bloody worth it. These sabaclsous glands, they produce a sweat. Somthing like that (i went to my docs). I suggest you do it too, just in case. I cant see the pice btw, but your description is right. If you want me to see them to conferm, give me the url or email me with a jpeg format.
hope this helps.
No worries
