Boyfriend follows sexy instagram accounts?

Soo my boyfriend and I are in love. We have been together for about 7 months now. he's 24 and i'm 20. I've always noticed that he follows a couple of sexual accounts on instagram. I get this can be normal, but it still hurts my feelings a bit. I would rather understand why he does this then show my insecure side when we have been so so good. can someone explain to me why guys do this? should it make me feel this way?
