anal orgasm
An anal orgasm is an orgasm that is achieved by stimulation of the anus. This type of orgasm is usually brought on by anal penetration, such as with a penis, fingering, anal beads, or an anal vibrator. This type of penetration can indirectly stimulate the G-spot in females and directly stimulate the prostate in males. Some males and females, however, may even experience anal orgasms through analingus (rimming).
