The original event page uses terms like “light bondage” and “light biting” without defining them, and does not talk about pinchy toys, buzzy toys, and suction toys. I hope that everyone at these events understands those terms the same way, and that male rats know that penetration is not the only fun thing you can do in bed.

Edit / the event manual mentions zappy toys. In my experience those are a rare taste but you do you.
