I am 29 years old married person. 4 years completed of my marriage. I am facing a strange issue since my marriage. I do not feel any fun, happiness of pleasure in sex. All the things are good timing erection. Still no pleasure. Each and every time whenever my mood is up I am not to enjoy. My wife all time satisfied. I do not know what is it even now in masturbate the same thing happens. I have done my all test like testosterone and other hormones test also. All are ok but still not enjoyable. When ejaculation happen I fill nothing or sometimes a little bit pleasure but during sex and ejaculation I feel nothing mostly. I wanted to try viagra I think it will add fun or pleasure but I feared about its side effects as I have no issue in erections.
