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 a whole arm. Stretch at your own pace; playing 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.
