I think the gloryhole experience is one for the free of spirit seeking the pure essence of cock and mouth - the act of either getting off anonymously in a total stranger's mouth or the act of getting a stranger off with your hands and mouth . . . not to mention other variations on the theme!
How convenient to have such a place to go to almost any time one has the urge for oral / penile pleasure whether they be M or F. I, for one, find it exhilarating that I can have that urge and get it satisfied without any drama in an anonymous hot and nasty setting most anytime day or night.
Personally, I have had the pleasure of giving a blow job and receiving one from both sexes - always anonymous which ratchets up the kinkiness just a notch. Truly - a great invention! I wonder if Al Gore had anything to do with inventing this mode of enjoyment like he did with "inventing the internet" - Hmmmm?
