Sexual issues and fantasies that I'm confused about?

This is an odd question about sexuality, I'm female, and I'm 20 years old. I seriously am confused with my sexual preferences. For a long time I didn't like the male body (in my early teens) I thought it was ugly, and the thought of intercourse was kind of disgusting. But now I can't quit thinking about it. It's almost like my sexual fantasies are running my life. But only the idea of sex. I've never had sex, the thought of actually doing the act makes me uncomfortable, but the idea if it controls my whole day. I think about it on the constant, and I can't help but be almost compulsive with masturbating, almost every day I'm doing it. And when I stay the night somewhere or go to families house, when I get back it's all I think about doing.

And I think it might be my lack of sexual experience, but it's making me explore other fetishes when I watch porn, that I would never do physically, but it's all that's in my mind. Also I find it weird that I can be turned on, not by something gross directly, but the gross things don't stop the want to masturbate. I can be watching a horror movie and get the sudden urge to masturbate, to which I'll pause and do so, and then continue the movie. I also have weird thoughts of often being controlled as in being submissive to another man, even though I see myself as not being a submissive type of person mentally, and these are all done in my head, but not by people I can actually obtain, only celebrities.

With the celebrities I often attach to one for a time, being completely enamored with them and only them for a period of months and then I will switch. And they are often different, but have personality traits that I admire. I start to act like they do or dress like they do, change the way I talk, and my speech ticks like they do and think about them sexually on the constant. But I'm never attracted to people I can actually obtain. I often without realizing it will be attracted to someone between the ages of 37-41. And I'm sure it has to do with the whole "Electra complex" thing which I like to look passed because I don't admire my father at all.

I will imagine this sort of relationship with them in my head like, I'll be watching a movie and think about what it would be like for them to be next to me as my boyfriend and then I watch the movie in my fantasy like I daydream while doing normal things. I like to act things out with pictures of them in front of me, like a faux scene in a movie and such, and try to dream about them every night, and I'll often touch my own face or hold my other hand like intertwining my fingers trying to get it to look like their hand is holding mine.

These daydreams control my whole day. I can be doing one thing and have a daydream while doing something else. I can daydream and do regular things at the same time.

I'm just confused and I know this is a long post but I've never mentioned it to anyone in my life, so I'm hoping to get a little insight.
