Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction. In much of a digestive tract such as the human gastrointestinal tract, smooth muscle tissue contracts in sequence to produce a peristaltic wave, which.

Orgasms can be achieved during a variety of activities, including vaginal, anal or oral sex, non-penetrative sex or masturbation.
