Went through bfs phone

Sooo I've been having the feeling of checking my bfs phone so I did just now and he draws girls and stuff it's true I see the pictures, but he thinks females bodies are art to draw, but i do porn and stuff so idk why i get uncomfortable or I don't like it when i find photos in his phone some of then are my friends which is weird asf but i do onlyfans and everyone sees it, but my question is should i be mad i mean he's never cheated he's just into drawing half naked women and then when i go through his phone i have to see it.
