I was in the shower, and as I was rinsing under my foreskin I noticed a sticky residue that was very thin and sticky. I know for a fact it is not smegma, it was like a thin film of plastic. It took a long jet stream from the shower head close up to slowly peel it off the glans. I have never had intercourse, and I'm only 13. Please help, I can not find any information about this anywhere.
