Premature Ejaculation caused by medicine side affects and seeking solution's to cure it.......

First of all i will like to describe the way it all started...I have been suffering from premature ejaculation for the past 9 years...... I used to masturbate since the age of 14 years and at the start of the practice for around 2 years, i used to masturbate regularly without any interval or at an interval of 2 days. I rarely masturbated for 2 or three times in a single day and most of the days did it only once. Gradually i decreased my frequency of masturbation and did it once in 5 days or sometimes continuously for a few days. I was a perfectly healthy guy w.r.t. sexual health and had no habit of smoking or consuming alcohol till that age. However at the age of 17 years i gradually developed an allergic problem called Sinusitis and for the treatment i went to see several doctors. In this duration i was staying away from home preparing for some entrance examination. The sinus allergy made it impossible for me to carry on my studies as i used to have a severe burning sensation in my throat and nose for most of the days. I used to lie down on my bed and was unable to go to coaching or study anything. I finally decided to see a doctor and in the process regularly switched many doctor's, if the later was unable to provide me relief. I consumed the prescription's given to me by each and if i found that the doctor prescription's were not working on me, i changed the doctor. It was 2003, the year which i can still remember that i used to be on medication for almost everyday consuming at an average of 5 tablets. I can't remember the name of the medicine's but some of them were in the range of 300 mg-500mg. This consumption of unaccounted number of tablets started having it side affects and i used to have 2-3 mouth ulcers at regular intervals. For this too when it started getting regular, a doctor prescribed me vitamin B tablet and the ulcer used to get cured as i consumed the vit-B tablets for around 3-4 days regularly (which i still take in case some ulcer appear). At the start of 2004 i had stopped taking the allopathic allergic medication and went home before the results of the entrance were out. Something really bad happened there at home, i had ulcer's at each and every corner in my mouth, even the tongue was not spared. They were so much in number that it became impossible for me to even talk or eat anything. I was shown to a doctor and some number of antibiotics alongwith some injections were prescribed and i was cured in around a week or so.... and still in 2012 while writing this i have an ulcer....:)... In short if i say my life was ruined bcoz of the medication that i took between 2003 & 2004. Please bear with me as i really want to tell about all the sequences which ultimately led to P.E, i am almost there.... In June 2004 i took admission in one of the engineering colleges and was not having any trouble w.r.t. P.E. till that time. My elder brother marriage was held at 19 nov 2004 and i was fine till then and believe me when i say this. After the marriage, i went back to my college as my semester exam were approaching. This is the time and i still remember that i had this gut feeling that something, something is really happening around the lower abdominal area, however i was not sure and used to ward it off thinking i am being too much paranoid about diseases. In the last days of December 2004 i was at home after taking my exams. After a few days of stay at home, one day i was really getting bored and just thought of getting some porn movies to watch ( which i regularly used to watch in my college too). I secluded myself to one of my rooms with a T.V. and as soon as i played the porn movie, what the hell !!! i was shocked, shattered and embarrassed, i ejaculated within a few seconds...what the f**k, i thought that it might have been due to some excitement. I kept the rented Cd's for the next day to check again, the next day again i ejaculated within a few seconds..I was now confirmed that a new problem had started and i was unable to sustain my ejaculation. I had some knowledge of this problem as one of my friend studying in XII class had a similar problem and when he told me about this problem i used to laugh and say hey man its nothing you are just getting excited, its fine and learn to control your excitement. What i meant to convey through my long story is, i hardly believe that i have any psychological problem that adds to my P.E. problem... and if somebody thinks to refute this.. please read my complete story once again and make me understand how is it possible that in a mere count of 30 days or so, i became from a non-Premature Ejaculator to a patient with Premature Ejaculation. I have already seen some of the best psychology department doctors available in New Delhi... and the most painful statement that i come to hear from them is the same, its psychological. Why the hell, any doctor doesn't try to study the situation's that led me to this problem, why do they have the same answer, why? The medicine they prescribed is an anti-depressant which is Fludac 20 or Paroxetine 25 mg. The medicine Paroxetine was recommended for 1 month and i took it regularly. It did benefit me and i was again temporarily normal but as soon as i stopped it after a few days 15-20 say, the problem started again. I want to ask, is taking an anti depressant o.k for longer duration, as it does improve my situation a lot? Why its okay to them that a person can have a Dysentery, Diarrhoea and similar disease and not a disease related to sexual function's? What really makes them believe this? I do not refute that some people may have psychological problem but not all. Please give me some medicine's name from any form of practice be it Ayurvedic, Unani, Allopathic or whatever, that has helped any of you get cured from this problem. I am totally frustrated and its really impacting my career. I have left my job for the past 1 year, doing a lot of exercises, consuming some ayurvedic medicines, got admitted to one of the natural therapy hospitals for 1 month, in short i have tried it all but am messed up... nothing has proved useful!!! the problem is still very intact I think that my problem is due to some possible side-affects from the large no. of cold and allergic medicines which i took because the problem started as a reaction to the medicines i took. I have read from one of the post that a certain cold medicine named Pseudoephedrine also causes P.E and also may be due to some prostate infection.. Please guide me how to get rid of the side affects of the above or what are the check ups for the same, if any... i don't know what to do more... please please guide me.... if any of you have been cured from this problem, please write to me the steps you followed to get cured, the medicine you took, all of it....please.... i will be very thankful to any of you who assist me achieving me a cure and will personally contact to thank you once i get cured that's a promise!!!! waiting for your responses ......
