Wondering if this plug will stay in place, without, assistance, during intercourse. I have a medium classic butt plug, which I've attempted to keep inside during intercourse, but it pops out at the most inconvenient times. It has a diameter, at the largest point, of 1 3/4 inches and drop off to 1" at the neck. I thought it would stay but does not. Has anyone tried the gumdrop triple bubble plug during intercourse "successfully?"
