There are groups in my area, where the guys all jack off together, called Jack or a variation of the word. Ladies are not allowed. Damn'it. A co-ed group for masturbation is called a Jack and Jill group and includes all gender types. There are not any in my area. My fantasy would be to have some naked gals, including me, masturbating, with a bunch of guys surrounding us masturbating in a circle. Then, the guys could shoot their load arcing over the ladies. That would make an awesome photo and video.
