I am 33 male, have a history of pornography and have been masturbating every day for the last 20 years. I have had several female partners in the past and was leading a healthy sex life until 1-2 years earlier where my problem started and got worse gradually. I doubt, I might have suffered from depression for the last few years, with stress from work and the stress of living abroad and lost some of my hair. I have suffered from scalp acne and have used low doses of roucoutanne for 2 X 6 months during this time. I am off the drug for a year now. Nowadays, I have very infrequent and weak morning erections and I can no longer get hard eneough to masturbate when alone, but I can sometimes have sex with my girlfriend. I can have intercourse with my girlfriend expecially in the mornings. I have experimented with viagra, 1/4 of a 25mg viagra is more than eneough for me. One thing I noticed is that just after having the pill, I can get erections in 5 mins. I sometimes think this is a placebo effect until the real effect of the drug kicks in. Apart from that I am perfectly healthy running half marathons, exercising 3/4 days a week. I have had my testesterone, tyroid and prolactin levels checked and all are ok. No blood pressure problems. Not smoking, very little alcohol and healthy diet. Not using any medicine. I have stayed away from sexual activity, porn and masturbation for the last three months but the situation has slightly improved. I have started having wet dreams (the first in my life). Do you think my problem is organic and psychological?
