Porn?

So my Fiance and I are open about almost everything, including porn and masturbation and all that.

At first it was okay because I never noticed him watching it often at all.

Now idk why but I've been getting a little discouraged. He looks up very specific things sometimes that I had no clue he was into. Or he'll look up a certain type of girl and I'm just like.... Well she's nothing like me nor did I know he was interested in watching that. Soooo could someone please make me feel better about this? Like are y'all comfortable with it? Are there times y'all feel discouraged about it?
