Mental vs. Physical Chastity—Which One is More Intense?

I used to think locking up was just about the physical aspect, but damn, the mental part is where the real control happens. Knowing someone else decides when I get relief messes with my head way more than the device itself. One thing that really cranked up the intensity for me was daily teasing without ever knowing if today’s the day I get released. It makes the whole experience way more frustrating but also way more rewarding. But I’m curious, do you think the mental aspect of chastity is harder to handle than the physical part?
