I am rajiv sharan, am 62 years. Used to be heavy drinker but now have left it completely since about 5 years. I suffer with ED (no erection) since very long despite having strong sexual desire. Even during extensive foreplay my organ remains limp and despite strong desire I do not feel sexual excitement / arousal. About 2 years back my friend advised me for Caverta 50 mg. Initially it worked wonders but became ineffective after some time, even though I took it occasionally, twice or even once in a month, I increased the dose to 100 mg but that also, after some time became ineffective. I do not know why. Does it happen with all allopathic ED medicines like sildenafil? I have been trying, since long, homeopathic as well ayurvedic treatments but nothing seems to work. There is this psychological problem, which I feel may be the reason - whenever I try I am obsessed with failure fear and no matter how much I or my wife try to dissuade it, it does not improve and no matters how much I or my wife tries there is no erection. And if at all there is erection sticky fluid (not semen) gets discharged and whatever erection there is, dies. Doctors advise me to avoid such thoughts, but how can I, it aromatically creeps in mind. I am now advised to take razzle 5 or 10 every night and told that though it will not give erection immediately but it will be a long term treatment. I have started using it and feel slight improvement, not enough to cause erection but nevertheless an improvement. But will it also become ineffective like sildenafil I took earlier. For how long should I take it. I personally feel lack of sexual arousal is the main reason of my ED. Another thing- I used to masturbate a lot earlier.
