The discomfort in trying to pull out of the Points of Intrigue makes it less than desirable. More than likely, the five lines that would appear along the shaft would be quite noticeable. Even if this is accomplished, getting back in while in a flaccid state could prove to be very interesting. While in an excited state, it could prove to be even more challenging! The Points of Intrigue are manufactured out of Polycarbonate. This item consists of semicircles with three different point lengths. The point lengths are approximately 1/8'', 3/16'' and 5/16''. The points have a slight buffed tip to avoid cutting into the penis. The tab located at the top provides easy installation by running the locking pin through the hole.
