Is my boyfriend a pervert?

I have been dating a guy for 1 year. we are in the same class. i proposed me in 1 month of being freinds even I gave in. we got very close very fast. he has the habit of lying about insignificant things and making up stories. But recently I found him having an another instagram account where he follows all sexual and nude accounts. He follows them on telegram and is even added in some whatsapp group where they share nudes not him but people. His gallery had nude pics and videos of many girls. He even finds one of our 40+ teacher hot and Is always commenting on her figure. His feed is also full of girls. He is a nice guy like otherwise never even forced me for sex and our female freinds feel safe with him. I don't know I am confused now
