Sorry if you guys have seen this.
"A new generation of anti-impotency drugs that are rubbed into the skin could prove more effective than Viagra, research indicates... the therapy, nanoparticles that release the anti-erectile chemical nitric oxide are rubbed on the problem area, and absorbed directly into the skin....Researchers also believe that the nanoparticle therapy could work much more quickly than Pfizer's market-leading drug, which takes up to an hour to kick in"
Of course I'm sure any new drug release would be far off. It would be great to just use small doses everyday on there though.
p.s. not sure what they mean about the anti-erectile chemical NO
