Cranky feeling following orgasm

I’m relatively new to chastity yet have some background in controlling or denying orgasms, and I’ve started spotting a trend: after being permitted an orgasm, I tend to become irritable and withdrawn for a day or two. Does anyone else experience this? What suggestions do you have for handling it? My partner and I are in a 24/7 dynamic where she holds the dominant role; I worry that my constant grumpiness whenever she allows me to climax makes me seem like less than an ideal submissive.
