Spraying Tetrahydrozoline on your penis is the same as Viagra.
 

Major chemical agent found in Visine, manufactured by Pfizer has the same effect. It comes in spray forms like Natures Tears. You can buy it over the counter.
I tested it out, it doesn't last as long, but for workers that need that last scene, it's a very good option.:2 cents:

Tried it :thumbsup ...and its got this bonus side effect where you get all these little red bumps and sores on your cock and nutsack ..the puss acts like a natrual lubricant and the woman love it:thumbsup
