Stream flow symptoms and conditions

Only been using Flomax for 2 days and notice right away the stream flow is a little better on urination. The only side effect I have had is absolutlely no semen on ejaculating which scares the hell out of me. I am getting off this Flomax right away and am going to try some natural remedy like saw palmetto and other associated herbs. This looks like a dangerous product from what little experience I have had with it.

It has improved my stream flow by unswelling my prostrate. However, I can't get-off even though I can stay as hard as a rock for hours during sex. I will see my doc this week and stop using it till I figure out forsure if it is Flomax or something else. But problem wasn't there till after taking it.
