I'm a hypocrite 😞

Why is it that I enjoy porn (maybe once a month) with myself and don't think anything is wrong with it...but when I see my husband was indulging, it upsets me? We have an awesome sex life and he only looks maybe once a month like myself...so why do I care so much?! I hate the fact I'm being so hypocritical and putting double standards on him. I talked to him about it in the past and we both feel the same about the occasional use of porn..so why am I feeling so betrayed?
