Introductions discussion

Hello there! I am just joining the group and wanted to say hello. For about three years now, I have been dabbling in chastity on an off-and-on basis with a wonderful professional Domme who is lovely to be around. I feel like it’s time for me to commit to long-term locking under her guidance. So far, my best record has only been about two days (using a CB6000), so holding out longer feels a bit intimidating right now. I would appreciate any recommendations on devices that work well for extended wear—I exercise quite regularly and need something gym-friendly—as well as some encouragement:-)
