Is it the same thing as porn?

DISCLAIMER: this is NOT a post to discuss whether you allow porn in a relationship. Let’s not beat that dead horse again.

I recently downloaded twitter (which, I know, is outdated and it’s embarrassing that I didn’t have one before now 😂) and I went to my boyfriend’s account and followed him. He posts a lot of funny memes, so I was scrolling down reading some of his posts until I came across a few from when we first started dating. They were all videos and pictures of the same girl that he’d retweeted. Some were of her shaking her ass, one was of a guy messing with her tits, and another was of her completely naked with only a gun covering her torso and a stormtrooper helmet on and it said something along the lines of ‘the only stormtrooper you’ll need’.

Listen, I literally could not give two fucks if he watches porn but I think this is too far and not the same thing. He argues that it’s just like porn.

Question: is it the same thing as porn? Why or why not?
