I could sit here and list all the positive benefits of chastity, as there are many. But really, those don't matter. What matters is worship, and devotion. Are you devoted enough to give up your cock? Give up orgasms? Give up all that control? Think of it like lent, to prove your faith. It's such a wonderful reminder of your place in life as well, one that is so hard to ignore even in the best of circumstances. A reminder of your Dominant's control, of your own submission. Give up control, hand over the key.
