I am EXTREMELY confused about my sexuality

Firstly I have a foot fetish but its pretty dominating in that Ive never really found boobs, vaginae, penises, anything a turn on except feet. Nothing at all. Also I much prefer mens feet to womens; I get turned on by the scent look and feel of mens feet, whilst with womens more only the shape and feel. Apparently after doing research this is a psychological problem which indicates I had a bad relationship with my father at a young age and thus now I seek a male scent as one of my turn ons, feet being the most obvious area to obtain it. I did have a slightly abusive father when I was young and Ive had this fetish for as long as I can remember; but anyways...

Recently, Ive set on a quest to try and normalise my sexuality, ie masturbating to normal straight porn instead of gay foot fetish porn. At first watching it didn't do anything for me but now I *can* get a very slight hard-on, but to be honest it still doesn't really do anything for me..
But now, very recently indeed, like the past two days or so, I've found I can get an autoerotic response (basic hard-on) whilst thinking of vaginas, anal/vaginal penetration and oral fornication and fellatio; even a very slight one whilst thinking about boobs! I can also get a slight hard on thinking about masturbating a man and having anal sex with a man; does that mean I'm bi? These feelings are still very weak though; about 1/20 the power of if I think of feet. If I was to keep up masturbating to ONLY normal straight porn for a long time, eg a year or two, would I become 'normalised' and lose (or weaken) my fetish?
