You want to push yourself, it's in your nature. Locking yourself up for short periods no longer satisfies you, but you're a little nervous, it's understandable, it's a commitment i promise you won't regret. Long term chastity is the natural next step, and with my guidance i know you will become a more disciplined and regimented submissive. You first week in Chastity will be a fulfilling and fun experience.
