Having an orgasm triggers a cascade of physiological responses, including the tightening of muscles in the pelvic and genital regions, and the release of various hormones and neurotransmitters. It sets the heart racing, ramps up breathing, and sends blood rushing to the penis or clitoris, causing them to become erect.

Of course reaching orgasm isn’t guaranteed. Before it happens, there's typically a sequence of desire, arousal, and plateau. An orgasm is marked by intense muscular contractions in the genital area and a profound sense of pleasure. Sometimes, this climax can lead to intriguing reactions.
