Here is part of my story (told August 2007):
My PSA was 1.2 in October 2006 and 4.3 in April/May 2007. Thus the concern I had at the time. See the link above.
First off, don't feel bad at all for asking questions. That's what the forum is for.
I don't think you have a cup full of concern from what I've heard.
If you are getting further tests, you should refrain from sexual activity a couple of days prior to the test, but ask your doctor for the straight scoop on that. Having said that, sexual activity won't affect the results that much.
Your PSA levels are very low. See the results of a Mayo clinic study at the link below:
Let us know how things go.
