Dear sir. I am facing low desire for sex and not erection when I see any sexual act or porn movies, during sex time and masturbating time only but sometimes I get hard erection when I do not need like morning and night and some other time also but the time when I want to erect I can not and ejaculates in few seconds. It feels like my brain is not excepting any sexual act and not giving signal to genital area. After lots of foreplay also I can achieve low erection and no desire. I used to watch more pornography and masturbate many more times may be daily from 17 of my age to 20 after that its been less. 2 months before my testosterone was also low 125 ng/dl but now my T-level is above 400 ng/dl. Still not satisfied.
