I used this app last year and am back. I used the meditation where you visualize a sexual encounter, and today I woke up with a morning erection which I haven’t been witnessing for a long time. I do the meditation right before bed.
Prior to bed to masturbate and edge a couple of times thinking about my girlfriend, then listen to the meditation before bed, and it’s working.
It really is all in the head. Me edging is making me want my girlfriend so much and is building my mental tolerance that my erection is possible and can bring me pleasure with my same partner, which I got in my head about.
Please try this for like a week and see if it helps you too. I will continue and update.
