would you be mad?

okay so opinions on porn aside, my boyfriend knows i don’t like whenever he watches it. i’m a self conscious person anyways so whenever i caught him watching it, i took it the wrong way and he swore he’d never look at it again. he also first tried to lie about it and say that he didn’t mean to click on it, but i caught him in the lie. recently, i looked on his phone to see he was looking up girls on instagram with photos that aren’t so... clothed. when i asked him about it, he said he was looking her up to see what college she went to. but when i asked him what college, he didn’t have a clue. i just don’t want lust to come between our relationship. i always tell him i don’t really feel like i’m beautiful or anything but he just denies it but then still pull this bs. i just need opinions, no hate, just honest criticism. thank you all! so glad i can vent on here
