Lesbian?

Okay so im about to get married in 15 days to a man.. but I’m so attracted to women and not really attracted to dicks. I’ve been told all my life its the biggest sin ever but I can’t control my thoughts even when we are having sex I think about women but I love him so much.. and I’m super jealous like I don’t even want him to see someone else naked.. please help me and could this be why I’m so jealous
