My very first oral pleasures, before sex was a gleam in my eye-- were thumb-sucking and nose-picking. Thumb-sucking everyone seems to give up after awhile. But the joy of picking my nose and eating my snot has deepened throughout my life, and this century booger-eating has become one of the specifically sexual huge turnons that are part of my complete development as a bodily fluid recycler and exchanger.
I have films of the most extreme nasal autoeroticism you will ever see. It's not on the net. There is in fact nothing like this on the net, I can assure you, because I have been searching semi-regularly for the most of two decades. If anyone is truly interested, they should send me an email address in response to this post, and I will write back, and depending on our conversation, I may send photos, a film, or more than one film. This is too hot and unique to post publicly.
I have only had snot and saliva-swapping, nose-eating sex (in the course of gay sex) once in my life. I have long hoped there's a man who wants to blow his nose right into his partner's mouth, and have the same done for him, someone who REALLY wants to get into hard-core mutual booger-eating and saliva swapping, along with any and all other bodily fluids and excretions.
