Porn envy. 😱

So this is just something that I have thought a lot about. My boyfriend is 24, and from what I understand watches porn a couple of times a week when we are on opposite work schedules. Totally normal and not worth getting upset over. Right?!? Any time I know he has gotten off without me here I feel totally 1. Gypped 2. Jealous because he got all hot and bothered without any help from me 3. Mixed feelings about him getting busy over watching some other woman. I get that it's totally normal and I can't be hypocritical because I love watching porn.. But why do I feel so jealous when my boyfriend does it? Anyone else have mixed feelings about this subject? Advice or insight?
