Chastity and orgasm denial discussion

I’ve mentioned this before, but for anyone who doesn’t know, my wife is in recovery from major surgery and it’ll be several months until she can have sex like we used to or even lie on her side without needing lots of pillows and rolled towels. She wants me in chastity, though teasing me has been a bit tricky, so I shared some concepts with her based on what I’ve seen online. I’d love more suggestions that don’t require much physical effort from the KH (Key Holder). Here are the ones she liked so far:

Ask me to take a cold shower instead of being teased when I’m really craving sex; she’ll let me know when it’s okay. Let me 30 seconds to masturbate and try to cum. This is quite popular on forums. Supervise my masturbation by controlling my speed and whether I stroke or pause. Sit in a chair while I stand with hands behind my back, edging me. If I get annoying about sex, she’ll have me shave my legs like I did for her previously, keeping these shorts as my year-round pants. Since I have decent leg hair, people will notice the difference. She’s had me wax my pubic and underarm areas before but never my legs, preferring not to do things that are too visible.

That covers it so far; hoping for some realistic ideas. We aren’t huge on D/s dynamics beyond what helps control an orgasm—no being her slave or kneeling required. She enjoys having her feet licked, though only when she’s horny, which won’t happen often according to her. That’s why I’m on a once-a-month schedule now. I prefer options focused more on teasing than submission overall. Thanks in advance.
