This was our first **** ring and now my guy and I are seriously hooked. I was a wee bit nervous on spending much at all because we weren't sure how he would like it, if at all. But I love Tantus toys, and knew that at least our first experience would be with a top notch toy so I went for it. I am super glad I did, this really is the PERFECT beginner C-ring. It's made from high quality silicone, so it has no taste or smell (which is great for me during blow jobs!) and is incredibly durable! I definitely think we will have this for a very very long time, if not forever. The ring is thick, with rounded edges for comfort (my partner can attest!) and an inner diameter of 2" which is pretty average. The silicone is somewhat stretchy, and very flexible. Just make sure you put it on before the **** in question gets at all hard! Another thing my partner found helpful was to put each of his balls through first, and his **** second. It's totally comfortable, and a nice snug fit once he's hard. And ohmygod it just looks so damn sexy. My partner definitely enjoys the way it makes his **** look, all dressed up and hard as a rock. Plus it adds greatly to sensitivity. The way a **** rings works is that it keeps blood from flowing out of the *****, and only allows it in. It makes your **** fat, veiny and SUPER hard. The Tantus Beginner C-ring performs beautifully and I would HIGHLY recommend it to anyone looking to start out with **** rings. We just love this product and can't say enough good things about it.
