A coregasm is an exercise-induced orgasm that is typically caused by the contractions of the lower abdominal muscles, which can contract the pelvic floor, leading to orgasm. It is more likely to happen as a result of abdominal exercises, such as leg raises or upper-ab exercises. It can be experienced by both sexes. Coregasm doesn't occur for everyone, but it is possible because the core muscles attach to the pelvic floor, which is responsible for the rhythmic contractions that occur during orgasm.
