I'm sexually confused... really confused

Ever since I was younger it was there. I liked boys. I never wanted to admit I just acted as if it was harmless and frivolous. Nobody needed to know. I even remember going on the computer and looking up gay porn and just browsing and doing that everyday until I almost got caught . Couple years later I have admitted to myself that I like guys ( I still remain in the inconspicuous closet ) . At that point I labeled myself as bisexual . Seeing as how I've dated girls all my life .but now I'm wondering if I even like them . Im not appalled by females or anything but the act of engaging in sexual activity or romantic activities bores me unlike where I would be with a guy. And I only masturbate to gay porn and I have trouble getting an erection with straight porn ( I've tried ) . I can picture marrying a girl and having kids but maybe it's just because what society has forced me to endure. A man and woman marrying . But I can also picture myself marrying a man . I want to have sex with both sexes to prove it but that would be inhuman . How could possibly come out ( which I also struggle with due to the fact that I live with a coven of homophobes ) if even I'm unsure of my own sexuality . Idk how exactly explain my feeling for woman
