Has anyone try it for ed?

What is it and what is it suposed to do ? Sorry If I am asking stupid questions.

Its an approved cream rubbed on the tip of the penis and will give an erection lasting at least an hour.  Can only get it thru prescription from your urologist.  Seems to have enough evidence that it does work.

and this is one thing I saw.
Nitroglycerin cream or gel increases blood flow to the penis. However, it is currently not approved by the FDA to treat erectile dysfunction. Older studies have found that nitroglycerin gel can enhance blood flow to the penis, but this increased blood flow may not be enough to sustain an erection.

This sounds like a treatment for angina pectoris (similar to nitroglycerin sublingual tablets).  Its usual intent is to lower blood pressure immediately and substantially.  
.
WARNING:  watch out if you also use PDE5 inhibitors (Viagra / Cialis class dick pills) !!!  The combination can lower your blood pressure so much that you pass out or worse.  
.
More generally, do your research in the medical literature (Google Scholar...) and not here!

(Folks who handled dynamite used to complain of headaches due to nitroglycerin absorption messing with blood pressure and blood flow. )

did a 90% blackout behind Viagra in the downstroke or was it the upstroke?
But the Kgirl and I were very close, and she was very cool and didn't panic.
I did feel bad and apologized if I made her worried at all.
Changed up how I take my meds now!

Possibly more snake oil, but I would love to hear about any RW experience ?
