Is it normal to fantasize about my father?

Hello, I am 20 years old, turning 21. I am happily taken by my boyfriend who is 23 years old. a very committed relationship!

My story starts back when I first hit puberty, I did not know I was gay back then, but as i grew, so did a deep attraction to my father, I don't check him out, I don't think hes sexy, but I've always wanted to see his business. I've always wanted to jack off with him, I've even had actual dreams of it, a lot of them. sucking it, swallowing, even just sitting there while he touches it acting like nothing is going on(ALL IN DREAMS)
when I was young I would find ways to end up seeing a glimpse.
one recent encounter was accidental, walking in on him taking a shower, his shower is clear glass so I saw him jacking off and immediately I was turned on.
..
My whole life so far, I've ignored it, and plan to keep doing so. but I always want to catch him in the act or see him naked.. I just ignore it. I have to.. for myself and my boyfriend.
Is this normal?
How would I talk to someone about these feelings, who would i talk to?
