I wouldn't use that shit....a lot of people have died from using that stuff as its highly poisonous.
Why would Melvin Goodrum need a drug to relax the splinter muscles for anal sex but increase blood flow to the penis allowing one to get harder and last longer?
All he'd have to do to achieve this naturally is run across a 6 pack of discounted expired chicken breasts at the Piggly Wiggly & he's already there.
The sight, smell & low low price is enough to get Melvin Goodrum aroused better than any popper could.
