Hanky Colors | Gay Sex Signals. The Gay Hanky Color Gay Sex Signal Code is thought to have originated by gay men in San Francisco after the Gold Rush, when, because of a shortage of women, men dancing with each other in square dances developed a code wherein the man wearing the blue bandana took the male part in the square dance, and the man wearing the red bandana took the female part (these bandanas were usually worn around the arm or hanging from the belt or in the back pocket of one's jeans. Handkerchief code or hanky code (also known as bandana code and flagging) is a way of indicating, usually among gay male casual sex-seekers or BDSM practitioners in the leather subculture in the United States, Canada and Europe, whether they are a top or bottom, and what kind of sex they are seeking, by wearing cotton color-coded handkerchiefs (bandanas), usually in the back pocket. Hanky code was widely used in the 1970s; it is much less common today, but can still be found in some areas. Today the bandanas are worn almost exclusively in the rear trouser pocket, on the left side of the body for tops and on the right for bottoms, just as tops wear their keys on the left belt loop and bottoms on the right. In the past bandanas might be worn tied around the neck (with the knot positioned on either the left or right side); around the ankle (when wearing boots or when undressed); hung from the left or right side of the belt, or on other parts of the body. There is no universally understood color code, and regional codes vary widely. There is general agreement upon the colors for more common practices, particularly those with an intuitive relation between the color and the practice, such as yellow for watersports; brown for scat; and black for SM, but no absolute consensus for less common practices.  What is listed on this page are the more common color code meanings. - Gay Fisting Videos .Com
