    Great Product, I really would love to see a tapered version.

    I have purchased three different versions in total of these sleeves. First off, great product - very comfortable and the material feels great for my wife! I would highly recommend it, for some spicy sex.

    Feedback:

    1.) The ending before the tip needs to be tapered, making the the circumference and diameter of the hole smaller. The base and mid shaft always is larger than just before the tip - creating a small gap.

    2.) Lengths should likely come in 0.5" increments, as you want the opening to be as close to the underside of your head as possible.

    Tips: I do use an electric heater, normally used for cramps, to get the sleeve nice and warm before use! My wife did mention that one of our sessions was a little off putting, because the sleeve was cooler than my body temperature - so that I was a quick and easy fix.

    Be sure to go slow, even the slim versions add a significant amount of girth! I would recommend introducing the smallest and shortest version possible, first, gain the interest - then move up to the longer or larger sizes. I started with a non-slim model and almost lost the wife's interest - flat out - I was just too big.

    Measure from the base - no pressing what so ever - to where your penis head start in cm.

    5" models = 12.7cm in length.

    4.5" models = 11.43cm in length.

    4" models = 10.16cm in length.

    Don't buy a model that has a greater length, than your measurement! Example: From the base (non-pressed!) to where the tip of your penis head begins is 11 cm, if you…

    My wife was very satisfied with the product. Our first experience I entered from behind. My wife is not a fan of sex toys so I wanted to discreetly test it. She received it well and repeatedly pushed into me taking the additional 25% without complaint. It maybe time to size up.!!
