Getting to 90 days with many questions

Hello everyone, Im Nelas and I started PM in October of 2020 ,we may call it PMO as I was pretty sure I wasnt gonna get laid with Covid and quarantines in these 3 months.
A friend pointed out to me that I may have had a porn addiction (which he was correct about). And Im proud to say that I left porn for good but I still have many questions left to be asnwered.
I still have sexual urges from time to time that I dont give in not to even marturbate. 1.If masturbating is supposedly a healthy and normal behavior why shouldnt we do it from time to time? Not that I want to go back to was I doing before, but all on good measure doesnt seem harmful.
2. I dont know if masturbating again as I complete my goal of 90 days PMO will harm what Ive accomplished.
3. I want to re engage on sex but im afraid of the first time I go back I wont be able to endure much and have a bad comeback experience to it.
If anyone could shine a light to any of this questions or share their knowledge and experience on it would be awesome, thank you all for reading.

 

I came here because a friend told me about symptons of porn addiction ( which I didnt believe in) and realized he maybe right. I was searching harder and harder emotions as the usual stuff stopped being enough to get off to and even harmed my sexual life with some instances of PIED. So I decided to quit porn and stopped masturbating (which I did a couple of times back then) and I can say it has changed my life for the better. But I dont know if masturbating again will come and bite me in the ass and come all full circle or as I have changed, nothing will happen and all just keeps been good.
Ps i had to delete the links on the links on the quotes to post this.
