Cramps because all women suffer from it

Try giving yourself an orgasm to stimulate the release of feel-good chemicals like dopamine and serotonin. The natural pain-relieving effects of these chemicals can ease pain from menstrual cramps, and the afterglow of an orgasm relaxes muscles.

When masturbating, some people enjoy using a vibrator or watching something sexy to get in the mood.

Idk man, that sounds bloody hell.
