6.9

A sex position similar to the sixtynine, but when a girl has her period during the 69. It can occur with lesbians or with straight couples, however gay guys are typically safe from this phenomena of bloody discharge. It is named as such because it is 69 interrupted by a period, hence: six point nine.

Guy 1: Dude, last night this girl and I were 69ing when she had her period on my face! It was nasty!

Guy2: That sucks! I hate 6.9s.
