Talk to Urologist on Anorgasmia

Hi,

I am unable to achieve orgasm while awake. I have experienced it multiple times during wet dreams while sleeping but I am unable to maintain erection, achieve orgasm as well as ejaculate while I am awake. I am unmarried and my only source of arousal is sexual thoughts or watching such content. I think it was only once that I was able to achieve ejaculation a few years back (still not so sure if it was semen or just a pre-cum).

Why am I unable to masturbate? Do you think its a psychological issue? Can you please help me out?
