Erectile Dysfunction

[julio]

I am a foreign worker in israel and as a common play here, men and women of diffent nationalities come to meet each other, dating each other and to best end, have sex. I am single, just 30 years old and i have a girlfriend whom I like very much, even in bed, older than me by 4 years. We had been together for more than a couple of years and our relationship still remains to be admirable. In the past two years, our sex life at the same time was great that it happend twice to us in the weekend when we meet, we had sex for sraight of 24hours and I had my orgasm for eight times and her´s I cannot count. For a man like me, it´s a lot outstanding achievement I´ve had. Regetfully, I month ago, I started to notice a difference in my sexual performance that until now I am suffering, I´m not sure if I can call it ED but what I felt is most likely to be it. I am having partial erections that I know wont satisfy my partner and sometimes would end up into nothing. I am taking 400I.U. of vit A daily and 3-4 gms of L-arginine but it did not help me. I am also using a penis ring to at least maintain erection but it was good only on my first three trials. I sometimes consider using viagra or cialis but I cannot take one because it needs prescription. Now I felt Im lost in nowhere and left by my trend. Please, If somebdy could possibly help me, I dont want to lose my girlfriend! I dont want to be crazy thinking of these mess!!! Thanks!!
