Chastity and orgasm denial discussion

Hello everyone! I have been into kink for a long time and have had an interest in chastity for some while now. My girlfriend surprised me by picking up on this interest to help fulfill my fantasies, though she has very little experience as a key holder. We are currently facing the challenge of being apart for another 7 weeks until I return to school, which is really tough. We are gradually stepping into this lifestyle by getting used to the cage through increasing periods of time with the lock on. I am just about to complete my first week and feel more horned up and devoted to her than ever before. We had a couple of questions about this way of life that I was hoping someone here could help us with.

1. We are looking for some funishments she can use on me to keep me focused on her thoughts. We want something involving humiliation, mild pain, teasing and denial, or maybe public embarrassment. (Since we’re newbies, any games or punishments you have in mind would be great)
2. I am trying to ensure she remains satisfied too, but it is difficult when I am completely lost in subspace while she continues her daily routine, seeming eager to meet my needs for subspace yet still wanting a functioning boyfriend nearby. Additionally, she mentioned that her orgasms feel less satisfying because they aren’t with me present. This is incredibly sweet and flattering, but I want her to be having mind-blowing orgasm moments while I wear the cage. Any advice? Thank you! -exploringcouple
