Is it normal to become attracted to women from lesbian porn

I'm a straight married 43-year old woman. I began watching lesbian porn a few years ago, and it's all that I watch now. Now, I get turned on sometimes when I stare at women's breasts and other features. I didn't feel this way before I started watching lesbian porn. I feel like I have corrupted my sexuality, but I can't stop watching lesbian porn. I never even watched porn before this, but a friend told me how she liked watching lesbians, because it was such a turn on. Well, now I'm addicted to it and I'm checking out women.
