My suggestion is that you ask Miss to be very strict, and impose a period of abstinence, when you won’t be allowed to touch yourself at all. Perhaps a fortnight is a good start.
During this week you will be expected to keep your mound and slit shaved bare, smooth and sensitive. You will not be allowed to edge, or in any way physically pleasure yourself.
For accountability, you can maintain a document in something like Google Docs, and share it with Miss. Every night before bed, write a new paragraph that states whether you obeyed the rules of your punishment during the last 24 hours, and refrained from touching yourself.
Then when you talk to Miss, you can describe how you’re finding your experience of abstinence, and thank her for being so strict with you.
It won’t take long before you’re aching to touch, and yearning for her permission to do so. Like the proverb says, abstinence makes the heart grow fonder.
And then, when she finally grants it, I don’t think you’ll have any problems climaxing…
