Ive only ever used strap ons that require a harness so me and partner were really excited to try this, i was also a little worried as i thought it might not stay in but i worried for nothing as it did perfectly due to the bulb being the right size. I found it very comfortable to wear for a long period of time to. I did find it a little uncomfortable removing but it's not a big deal. My partner found it very enjoyable and loved the silicone material. Will be using this strapless strap on a lot more than my harness ones and its a lot less hassle
