So, meet a new girl and went up to room the first night we met. My pp was broke (which is unusual), following weekend same thing... dead pp.... so, at this point I was worried so I talked to my dr. who said I was way too young (28) for any major ED problems. He thought it was pyschological with being with a new woman or stress (recent layoffs, death in family, broke up with pyscho -Borderline Personality Disorder ex). Anyways, he gave me 4 happy blue pills. So, this weekend the new girl came over... I popped 50 mgs 1 hour prior... and once again my pp was broken... but, in the morning it was back to normal and seems to be functioning normal sense. Can anyone explain why the Viagra had no effect and why the following morning my sex drive returned?
