The Depth Trainers are a firm favorite. They are designed to slowly stretch you deeper over time, eventually allowing you to take larger toys or an entire arm. Stretch at your own pace. Using this over a few months is best. When you’re ready and want more, get the next size up. Use plenty of lube, they are smooth so that they slide in easily, with no heads or bumps.
