Methamphetamine (AKA: Crystal, Speed, Meth, Ice, Crank-ALL synonyms of Methamphetamine Hydrochloride) that produces extreme elevation in sexual sensitivity. This effect is not exclusive to guys, so called "dick dope" affects women the same way. Sexual arousal is extremely heightened, the act of masturbation and intercourse pre-orgasm feels like a low grade orgasm during the entire duration of sexual stimulation. The orgasm itself can literally feel 10-100 times more pleasurable and intense than an orgasm without "dick dope" methamphetamine.
"I've never thought my body was capable of this kind of pleasure before I tried 'dick dope' meth".
