Porn in marriage?

So last night me and my husband decided to mix things up, well to be honest I did it for him.

He wanted to feel more excited and just do something different instead of us just making “love” you know just as people do in marriage.

Anyways I decided to go down on him while he was on his iPad, so than I decided to tell him to just start watching porn so it will make things different, he asked me if I was sure and I said “yeah” so he did.. I know for a lot of girls this doesn’t matter but my husband hadn’t really watched porn since before we were together.. but like any man i know he would enjoy so he did. Everything was great for him and he enjoyed him self.. but now Im feeling weird and it kinda bothered me that he got off by watching other woman and I feel like it was different the way he climax...yes even though I allowed it.. but now Im feeling like idk that he might like that more than just having sex with me.. am i just going crazy with my thoughts or what you do guys think?🤷🏻‍♀️
