Partner masturbating

Ladies, I personally masturbate when alone at home. Sometimes I just have to make myself orgasm. I don't feel that I am disrespecting my husband for doing so. I still have sex with him even if I've had an orgasm that day.

So.... I can't seem to understand why it hurts me and bothers me soooo much when I find out HE masturbates. I try telling myself "uhm you do it too". Lol. But I feel so less of a woman when he does. What the fudge. 😒😒

Any advice ladies.
