Is it normal to be confused about sexuality

I've been really confused for some time, I mean like today while half asleep I fantasized about having sex with a woman and when I woke up I went to see some porn and I was more turned on by the guy then the girl...I don't know why, I mean I think I have a fat fetish for men who have a bit of meat on them that I'm only attracted to, I don't like anything else nor have I ever fantasized about dick or butt or whatever nor do have I ever considered being like a dominant...I don't want anything of mine inside them, preferably I think its always been about me receiving. I don't stick anything in my anus either, I just fantasized about having sex with a guy in my non existent vagina. I don't have an emotional connection to guys and I find some things about sex just disgusting between them. :/ Also, I find it more harder to be aroused to women in porn, though I know I have been before, when I really focused on the women, it was hot...Am I just more attracted to one gender than the other or what? Am I bi?
