Lost

Im still trying to find out what i really like when it comes to sex, I lost my virginity to a boy at school a few months back but I had expected more, it was quick, uncomfortable and not a nice overall experience, after watching porn for over a year I thought that it at least would feel nice in some way but maybe it was just the wrong guy.

I watch porn a couple of times every week when Im home alone or when my parents are sleeping but the kind of porn that turns me on is the kind I can´t talk to my friends about, I watch alot of videos with younger, tied up girls being fucked by older men, I guess that it´s quite normal but I started fantasize about my dad a few weeks back and I can´t get that out of my head. Everytime I see my dad in his boxer or just without a shirt I can feel my cheeks getting red, my breating getting heavy and I´ve been caught starring a couple of times lately. I don´t know what to do, is it normal to have these feeling about your own dad?

And just a couple of days ago I stumbled over some videos of girls with their dogs, I got turned on and it grosses me out that my body had that reaction to these kinds of videos, we have 2 dogs and I have never in my life thought about people having sex with animals, why do I get turned on by things that is so wrong?

Im confused and I don´t know how to talk about all of this, I don´t know what to do, I feel like Im going insane and it´s kind of hard to avoid someone that living in the same house.
What should I do?
