Nitroglycerine Condom!
Here you go, limpy: a condom with an erection-sustaining paste, so that while the condom may reduce a little sensitivity, your cock is gonna stay nice and hard. The active ingredient is trademarked Zanifil, but theactive ingredient is glyceryl trinitrate. Yes, it's motherfucking nitroglycerine. If Mr. Nobel knew that his favorite explosive would be giving women orgasms left and right, the past recipients of the Nobel Prize would be far boobier than they actually have been. Thanks, modern prophylactic science, for making my penis' nickname, "Boom Goes The Dynamite", a little more true with every passing day.
