I have suffered from Inhibited Ejaculation all my life. I'm now 55 years old. This is a problem that is extremely hard to fix. I know I went to therapists off and on for 10 years trying to get it fixed. Mine was "situational" which meant that I had no ejaculation problems the first time I would have sex with someone, or during paid sex or one night stands. It was only when a relationship would start to form that my sexual functioning would shut down like someone shutting off a light switch. My marriage has been sexless because of this and we had to go to a fertility specialist in order for her to get pregnant. Luckily she has accepted the fact that this problem can't be cured and that I don't enjoy sex if I can't cum. Lots of therapists for told me what they THINK is causing it but they all say something different. From my own research it looks like some kind of intimacy anxiety.
