Hello Endof, welcome to the forum. You're in the right place for help and support. It's great that you're here and you want to be better, that itself is a great step.
I don't know anything about therapy and I can't really advise you, but i do identify with a lot of what you said. I used to have thoughts that i want to take my clothes off in front of women. I had forgotten about that but reading it here woke that memory up. I think that the more you give in to urges the more urges come, not always the same urges. For instance, watching porn makes the urges to masturbate stronger, and vice versa, and both will make the urge to see women in the street stronger. Lack of shemiras einayim can result in fantasies and make the urge to act out stronger. Is it possible that masturbating and porn watching is feeding this urge of your to take off clothes?
I think porn, masturbation, fantasies, lack of shmiras eiynayim and acting out are all basically the same thing, they are giving in to lust. Giving in to lust in any of its forms will just make the lust stronger. You may see one form of the lust as more of a problem than another, but it's all lust really and doing one makes it harder to stop the other.
You're saying that you're not so bothered by the porn and the masturbation, you're only bothered by the constant sexual fantasies and acting out. I'm suggesting that it's really the other way round. The porn and masturbation is making you act out and fantasise. Have you ever gone a while without porn or masturbation? If so how did it feel? If not, are you willing to try it?
I'm not saying this instead of therapy, I really have no idea about therapy. Maybe you do have issues with your father that need to be worked out. But i think you can work on this on more than one level.
I hope I've helped.
