You must train your body to produce pleasure internally. This involves fine-tuning the muscles and nerves in your pelvic region and using mental focus to amplify the resulting sensations. In traditional sexual activity, external stimulation from a partner or masturbation creates the conditions for pleasure. Your brain responds as a part of a cycle of arousal, causing your pelvic muscles to contract rhythmically, further enhancing your pleasure. In Aneros stimulation these muscles learn to spontaneously contract, allowing you to experience pure pleasure from the inside.
