The situation of a male who has not recently experienced an orgasm and/or ejaculation. The term is typically used by practitioners of edging and tantric masturbation to express the state or duration of successful avoidance of orgasm and/or ejaculation, despite regular sexual stimulation that would normally be expected to produce the same.
I'm 13 days uncummed. How about you?
I'd much rather edge for an hour a day and remain uncummed than to jack off in daily two-minute quickie sessions like some 12-year-old who has just discovered his penis.
