Female led relationships discussion

Hi all! The wife and I have been experimenting with chastity for quite some time. Usually nothing lasts too long, perhaps a day or two, occasionally stretching to three days (though that’s rare). But! She has grown increasingly dominant and is really enjoying the lifestyle of ruling over her slave. However, she can be rather heavy-handed and tends toward being a bit difficult, which after a few days starts to wear me down and makes me lose interest in being submissive. Lately she claims I don’t “play right.” Today I joked that she should step up and implement some punishment if she’s so serious about this lifestyle. Her reply was, “don’t tempt me.” My wife isn’t the type to browse the internet for chastity advice or FML posts… so it falls to me to suggest punishments for her. So I wanted to ask the couples here who use them, what kind of punishment do you utilize? I suspect others are in my boat as well. How about we turn this into an ongoing list of ideas?
