This is a sort of "how to" guide, by a gay male for anyone who is interested. Short self help guide for entertainment purposes only. There is no direct research, studies or medical references used in its compilation. It is merely a guide to performing oral sex from a gay man’s perspective. This is written by and intended for adults. It contains material of a adult nature. Some of it contains male with male sex. So if this isn't your thing, do not go any further.
