@ the OP:
I'm the one who posted about 2 or 3 posts above about the GNC Prostate product. I'm not a troll, I don't work for GNC, I'm just telling you that I had the EXACT same problem you have and tried everything including doctors, viagra etc. but this stuff works. I can't sit here and say I'm any kind of doctor, but I'm willing to bet your prostate is screwed up. Please just give it a try, you have nothing else to lose. It REALLY worked for me. I've quit smoking for up to 6 weeks with absolutely no problem down there, but after trying it for 2-3 days I started feeling normal again, like I was 18 again (I'm 23).
