Crystal dick

A former hustler who has been at this bar every night this week says "crystal dick" isn't a problem for him, but he has seen others rub their dicks so raw that they bleed.

Users also report that crystal heightens sexual arousal and increases stamina by delaying orgasm, and they report highly intense orgasms. However, after long-term use, the urge to ejaculate becomes all-comsuming. Impotence is a long-term consequence, and users develop “crystal dick,” which is the inability to have an erection.

The impotence drug finally gave meth users a way around "crystal dick," the erectile dysfunction typical with crystal.

Some crystal users report that the combination of increased anal sensitivity and crystal dick tends to make them “instant bottoms” (Frosch, Shoptaw, Huber, Rawson, & Ling, 1996; Heredia, 2003).
