This butt-plug does not stay in place without additional support (crotch rope, karada, rubber briefs or swimsuit with an reinforced crotch hole for the plug tube). But otherwise it’s very comfortable despite the size (length: 15.5 cm / 6.1 inch, diameter: 4.5 cm / 1.77 inch). I prefer this dildo even to the double balloon enema nozzle.
I was delighted with how comfortable the peg performed all day long when worn under my tights & leotard. No chaffing and very flexible for a lovely all day massage and reminder to exercise.
