Can you develop PE from edging?

Hi, I'm 21 and about 2 years ago, after having zero problems whatsoever, I started having problems with holding in my orgasms after a couple of minutes.

I read up fixes online and was amused to find that edging apparently helps you control your orgasms, me being relatively inexperienced with sex, only having 2 partners, I took this advice and ran with it.

A couple years later, regularly spending up to 30-40 minutes on my masturbation sessions edging, when I have sex with my current SO it doesn't last more than 15 seconds. Even when I masturbate it only takes about 10 strokes before I need to stop and start over.

My pelvic floor is strong enough to stop the flow of urine instantly with no issue, so that's been ruled out. I experience a mild form of depression so that may in fact be the root cause of my PE, but I simply can't believe that I still experience PE even after being so comfortable edging for long periods of time.

I am currently on soft-mode nofap, having sex with my girlfriend I feel will help acclimate myself and my penis with sexual intercourse. Hoping to god it will help, my self-esteem has taken a hit from this.

Thanks for reading, I've been lurking these forums for a sec now and I would really appreciate help from people who actually have experience/ know people who have been in the same situation as me. Advice on PE is hard to come by.
