One more new guy

Hi I am Eli, 26 from Israel and I really dig this site.

I want to tell my story, even if it will only be read by me.
I have a question for members of the community at the end so you can skip to it if you wish

I have been struggling with porn, bad sexual activity, prostitution and self harm for a few years now.
In Israel we serve in the army, and I think back then I started using porn and going to prostitutes as a means of suppressing my trauma and bad emotions from my difficult military service. Since then it went downhill, I spent thousands of dollars and hid it all up. I started fantasizing about trans women after being released from the army and the started going to trans-women escorts. I decided I am bi, attracted to sucking dick and not only to women, and slowly i lost interest in the real world and in my relationships - switching those with long porn sessions, grindr app meetups, obsessive tinder behavior and camming online. In parallel I started studying physics and Computer Science at TAU, today I am in my last year of studies. Porn addiction has harmed my grades severly, making me waste my time the first two years of school. Every relationship I had ended up in me running away, lying and cheating. A year ago I also started a bad habit of 'sugar-daddying', I got into those websites, lying to myself this is prostitution and fantasized about girls doing all I say and threesomes and the likes...also spent a LOT of money there, trying to accomplish fantasies that never really satisfied me.

5 months ago I started a new relationship with a woman that really makes a difference in me. I started therapy, I am now dealing with my post trauma and I am learning to feel and love myself for the first time in 26 years, I am also learning honesty for the first time.
I am pretty ashamed that I already lied to her twice - once at the begining i went to meet another girl without her knowing. and last weekend i met with a guy on grindr and also payed a couple to have threesome with them.
The lying was intolerable and I told her, and though she was very hurt and angry with me, she chose to say. She chose me. And I want to make it for her, because I truly love her and I feel this could continue to be a great relationship.
And here I am, i found out about noFap a while a go and it sounds just like the thing I need.
I hope to come out a stronger person, a grown up in my own eyes.

I have a question that I am pondering about, and I would really be happy if you take the time to share an answer :

I feel like I truly don't know if things that i became attracted to in the last few years - for me it is sucking dick, threesomes and orgies and swinging, sites like 'chaturbate', public playing, lite BDSM and experimenting sexually - are a part of my porn addiction or are they just the things I love. I am afraid of getting myself into a place to fighting my sexual urges and ending up unhappy with it. Have you had similar thoughts? maybe some conclusions about this kind of thoughts?

Thank you all! and good luck
