I’ve had them for a long time, but recently I was pumping and used too much vacuum without enough lubricant and the skin round where they were came of taking the papules with it.
Since then (like just now) I noticed some very tiny ppp’s and just removed them with rubbing them with my thumb.
I’m uncut so it does get slightly moist there which aids the whole process as it keeps the skin supple and soft
So following on from that You could try just wetting the area very slightly, Saliva might be the best as it is thicker than water, (and the enzymes in saliva might help to soften the skin, leaving it to get well moisterised (Inside a condom?)) and once the skin is very soft , just rub lightly over them with your thumb.
The trick will be to use just a little moisture so there is some friction by your thumb on the area. but massaging the area will tend to dry the skin so you will have to find a the level of moisture that suits you best.
Maybe worth a try. It can’t do any damage but might just take of the outer layer of skin and the PPP’s with it
But do not rub hard enough to take too much skin off as you will get very sore. And just try it on a small area first.
