Am I making a big deal about this social media post!

My partner shared a post of his female friend who raps which he’s never mentioned before nor who I’ve seen and then in the post she is being very sexual and dancing and twerking in the video and he commented and tagged her but then when I tell him I have a problem with it, this is what he says & mind you I did call him thirsty because he doesn’t post or share any of my businesses or content let alone a picture of us once since like April .
