The tingling sensation is likely due to the fact cum contains live semen swimming about looking for an egg to fertilize. After I've given head I swear I can feel the little buggers dancing around my tastebuds.
I've never tried it as a face cream but I can see how it might work as a cleanser. The swimming/penetration action that sperm exhibit could dig into the pores loosening dirt or other impurities. I would suggest if you're going to use it this way that you wash it off before it dries as dried sperm will clog your pores just as badly as any other caked on substance would.
The best a man can get.
I've grown it out to 70s proportions. I'm calling it my chastity pelt.
