17 y/o Male Who Has Never Orgasmed/Ejaculated From Masturbation Before

Hey everyone, I'm 17 as of now and have never before orgasmed from masturbation before. I have had wet dreams but I have never been able to ejaculate from physical stimulation. For background, I am uncircumcised and started retracting my foreskin at around 15/16 to find out that my glans was incredibly, and painfully, sensitive. Masturbation did not feel good at all, especially since I feel nothing from the shaft of my penis. The pain has improved a lot, but as of now, touching certain parts on the head just gives me the sensation of wanting to pee, and if I continue going, I do. What can I do to not feel this, but instead feel a good sensation that can lead to orgasm?
