Chastity and orgasm denial discussion

Greetings subs and doms/dommes, I’ve started a four-week denial session with my girlfriend, since we’re already apart and I thought it would be fun. The focus is mostly on denying orgasms, edging, and milking - though ruined ones were part of the plan, they might get banned later too. Plus, because I struggle to stick to her strict edging schedule (which ranges from 5 to 20 minutes a day), my session could stretch to five or six weeks. This leads to my question. For significant misbehavior, such as when I couldn’t hold back during an hour-long phone call, she spins a wheel of fortune we found online. I’m not sure of the exact settings, but it has numbers on it. The number landed adds days to my release date. Could you help us with punishments for smaller infractions? Part of our deal is that I provide her with a list of punishment ideas so she doesn’t have to keep spinning the wheel. I know this feels like topping from the bottom, but we’re new to this and someone has to come up with suggestions, right? I tell myself it’ll be a substantial list and there WILL be things on it that I absolutely dread. So far, my notes include minor rules like only allowing edging with my left hand, using just two fingers, or doing it under the shower head (risky since I’m staying at my parents’ place). I don’t wear a cage by the way. Feel free to share any ideas; ask if you need clarification and I’ll be glad to answer.:)
