methylene blue

I have been doing some research on Methylene Blue and it seems that it blocks the release of nitric oxide. Since nitric oxide is necessary for an erection could Methylene Blue cause erectile dysfunction?

After researching Methylene Blue, I have decided to give this a try. I ordered a pharmaceutical grade, premixed in a dropper bottle. Each drop is .5 mg. I’m going to start slow and see how it goes. Any thoughts or advice?
