Recission 2 - Repurposed
Since your length has already slipped back inside of you, making normal orgasm difficult... why not orgasm when you give oral pleasure to others? Repurpose the nerves from your re-absorbed length, add them to your tongue, and enjoy submissive oral service you give to others, as if it were the best masturbation in the world. But this one doesn't break that wonderful chaste haze you have going on. Themes of being more submissive to me personally are also included, and themes of how right for you it is to lead a chaste existence.
Training to give oral as an outlet for chaste desires, this is the right route... it's not like you can use your recessed length now anyway. Body transformation themes also reinforced.
