lesbian porn

Okay so I'm like really really sexually attracted to lesbian porn, and I don't know if it's a bad thing and means something or if it's totally fine, and I don't have to tell my boyfriend(of 2 years). I never orgasm when my boyfriend and I have sex but masturbating to lesbian porn or even just thinking about having sex with a girl gets me wild horny. But I love my boyfriend. What should I doo??
