Definition - What does Detumescence mean?
Detumescence is the process during which blood leaves the erect penis, returning it to a flaccid state. It is often a stage when the penis is subsiding from sexual tension, swelling, and sexual arousal. This can happen when an erection goes down or after a sexual encounter.
Kinkly explains Detumescence
Detumescence is when a swelling or an erection subsides. This can be a natural process after ejaculation or it can occur when there is a performance anxiety issue or difficulty maintaining an erection.
