Over time, chronic masturbation (especially involving prolonged edging) impairs a male's erectile competence. Total impotence may result, though rarely. The typical subject experiences cycles of alternating penile turgidity and flaccidity during masturbation, often ejaculating with a soft penis. MIED has been termed "Porn-Induced Erectile Dysfunction" (PIED), but the primary etiology is habituation to the unnatural intensity of manual gratification, replacing more diffuse rewards of copulation. Eventually the masturbator is unable to maintain or even obtain erection during penetrative sex and abandons his attempts at copulation. MIED is progressive and generally irreversible, rendering the masturbator pussy-free for life. --- [M4M] [masturbation] [chronic masturbator] [pussyfree] [pussy-free] [ejaculation] [MIED] [PIED] [erectile dysfunction] [impotence]
