I only like girl porn

For long as I can remember I only can get off to female porn. Mostly solos with big boobs. My friends swear I am a lesbian and just don't know it, because I've never actually been with a girl. I can only orgasm using my toy watching women. I tried using it while having sex with my man but I don't orgasm. And tried masturbating to videos he sends me of him jerking off but that doesn't work either. When we have sex I do get wet and it feels good. I know some women only orgasm off stimulation. But only female porn works for me. Anyone else like this?
