Couples these days are experimenting more with anal play, but it can be extremely intimidating. While it can be a very pleasurable part of play, it can also be a very negative experience if done wrong. The Trinity Anal Trainer Set makes it easy to ease yourself into anal play. Since you get all three soft jelly rubber anal plugs you do not have to commit to one size when you buy it. As a beginner you can start out with the smallest piece (1 inch wide) and try it at your own pace while you are alone. You can then work your way up to the medium sized (1.25 inches wide) and then maybe on to the biggest one (2 inches wide) if you feel like it. To maximize comfort, each plug is made from TPE. Measurements: , Small: 4 inches tall and 0.75 inches in diameter. , Medium: 5.25 inches tall and 1.5 inches in diameter. , Large: 5.5 inches tall and 2.25 inches in diameter.
