help from experts needed

• so July 7 ( 28 days of NoFap )
• i joined NoFap on 9 june, 2020 when suddenly one night i stopped getting erection @ porn or any pic.
• i have watched porn a lot, an used it to counter my stress form my studying, usual pattern was 2-3 hour study spaced with porn and edging, then same cycle whole day and finally an orgasm @ night on porn before sleep.
• i am a virgin, age = 23.
• there is no change of a girlfriend or marriage in next 2-3 years

positives

• more energy.
• sometimes i am able to get 70% erections by my mind and sometimes not.
• i get good night erections they are very regular and only time they occur less if i have a lot to study and not sleep properly.
• i got 1 nightfall unlit now.
• one thing for sure, if am in sound sleep if am almost always going to have an erection ( so physically i am fine, i am fit and workout regularly at least 4 times a week )

negatives

• i get high urge to ejaculate during day time and this often coincides with my ED, penis instead gets shrunk.
• when every i watch pic of some women randomly in google news feed so, i get this raging feeling to get erect but i cannot.
• it feels like semen in struck in penis and wants to come out.
• after that pic often messes with my mind and makes it difficult to get erection by my own imagination ( which is limited because i am a virgin )
• it feels like 2 forces, my mind can get an erection but external picture of women don't.

what you people suggest, who have gone through similar situations ?
