Porn and PE

I have an uncircumcised dick and when I'm retract my foreskin back it hurts a bit. Due to that reason I used to masturbate by rubbing the head of the penis while watching porn. Since my first sex few months ago, I was able to masturbate for quite a while watching porn and rubbing head. But my first sex with a call girl was a disaster. I ejaculated after few touches of that girl and I was aroused for the second time and had sex. But as my foreskin is hard to retract and painful I wasn't able to enjoy the sex as I didn't feel much. My penis was felt numb during intercourse as i pulled the foreskin and put on a condom. From that day onwards I feel I Ejaculate so quickly. My head is the most sensitive part of my penis and I feel it becomes huge and aroused so quickly after few touches. I feel I come to edge very soon and my head feels like a volcano which is about to explode. And I noticed If I ejaculated within last 24 hours, I can last a bit longer and my dick feels half erected and not aroused so much. But if i haven't ejaculated in some time i feel i get close to the edge quickly. I tried start and stop method, squeeze method and urination method but those things just stop the ejaculation temporary but after I touch the Dick again i feel i wanna ejaculate. So they haven't helped me to extend the time to get to the edge. My head seems so sensitive and it becomes pink coloured when i retract the foreskin and also it hurts when i touch the uncovered head. And after retracting the foreskin doesn't go back to normal position unless I guide them back. For your information, I have been taking meds for social anxiety for few years. Please help me. I'm really scared and worried.
