New Femstronaut here, with PSUB (but under psychological treatment)

Hey there everyone. I'm MinaClavero and I'm new here. I'm not sure if this site has a age restriction but I'm 17 years old, I'll turn 18 in March 2017. As the title says, I'm under psychological treatment since a lot of time, but it's only been one session since I opened up to my therapist and told her about my problem.

Here goes my story.
I've always masturbated, since I was a child. I mean... binge-masturbated. I don't even have a memory of myself about a period of my life without binge-masturbating (only did it for approx. a week in January 2016 because I went on a trip and I shared the room, but nothing besides that).
I've always believed masturbation is a healthy thing. Neither good nor bad; it's just all about evolution. But I've always used that as an excuse while jerking off from 3 to +15 times a day.
When I was a child, I used to think that was a disease. I used to think I had a serious illness and nobody should know about that because it was super secret and disgusting. I didn't even felt human at all.
In my purest years as a teen I remembered always doing it when I wanted to feel better because of a problem, fear, or something about my personality that I thought I could never change. I did it daily. And that is how it's been since now.
Although I now considered excessive masturbation a natural thing, I still felt deep inside it wasn't normal. These last weeks I've been reading some articles about masturbation in 2knowmyself (a psychology page) .The page states about the dangers of porn/masturbation addiction and then I wanted to know more and more (that's how I discovered this site also).
I decided to open up to my closest friend on Sunday 18th and to my therapist yesterday (Tuesday 20th). It was easy to tell my friend about my problem because she is very caring and loving and plus I told her via text. She understood me and encouraged me to ask for help. When I told my therapist, on the other hand, I had to tell her face-to-face and I was super nervous. I doubted all day about telling her just because of how nervous I was. And when I was in session and said her "I have a compulsion for masturbating" I broke up and cried.
What I want to clarify to you guys is that I don't use porn regularly. I just watch porn or images from time to time, like, once or twice a week. When I engage in this behavior I don't think about anything, nor I add it any kind of sexual meaning. Weird, right?
I started my rebooting process this Sunday. It's been four days for me. I can feel some of the effects already: I'm encountering myself with all the problems I haven't been facing. But I'm staying strong. I want to end all of this. I want to know myself without my addiction. I want to dominate masturbation; I don't want masturbation to dominate me.
When I finish my rebooting process I'm willing to masturbate again but ONLY when I feel REAL sexual desire,from time to time and when my brain chemicals are balanced. I hope I can meet here people which can guide me through this process, which I can share experiences with and I also hope I can help other people with this addiction when I get over mine. I'm really grateful I've found a place like this.

A big hug to all of you.
