Help! sex life is not good: new please read!

Hello. I just joined NoFap because I want to make a change in my life but I have to tell my story first. I am going to be a senior in the fall and my sex story has been complicated. I began masturbating in 7th grade was the first time I did it. I don’t think I started porn until eighth grade however. I remember after masturbating one night, I woke up barley able to walk. My nuts hurt and it was the most pain I had ever felt I my life. I was rushed to the hospital and found out I had testicular torsion. I had surgery ASAP and if I didn’t, I would have lost the testicle. I was also informed I have a varicocele on my left side. I masturbated still after the surgery; I seemed to have no problems even with the varicocele. Until one day, the unthinkable happened; I got a girlfriend. I had never had sexual contact with a girl besides making out at this point and was excited to finally get it done. I got hard and kept an erection; I couldn’t ejaculate. She sucked my dick for about ten minutes- nothing. After dating for 10 months and having vaginal sex about 2 times and head more; I haven’t (albeit she only does it for 5-10 minutes and stops). Is this because of my habit of porn, masturbation, the surgery, or varicocele? I want to be able to ejaculate in front of a female. And have kids in the future. I am a Christ follower as well which makes it even worse in my spirit how I have been addicted to it; relapse after relapse of porn and the pressure and temptation of sex in real life. Thoughts and advice- please! I know no one on here is a doctor but someone talk. Sorry for the read- all love.
