Sumata is a form of non-penetrative sexual activity where someone receives pleasure by thrusting their penis between their partner’s thighs. The receiving partner may also move and rub the penis with their thighs and labia. The thrusting usually occurs until the thrusting person ejaculates. Sumata is a form of frottage, or rubbing against another’s person’s body to masturbate.
Sumata is a Japanese term that directly translates to bare crotch. That’s because the people involved in sumata usually aren’t wearing any underwear. This increases the sensations enjoyed during sumata. The word sumata is also used as a synonym for thighs.
Sumata is usually practiced in the Japanese "health industry". It’s illegal to receive money for sexual intercourse in Japan, but the sector coyly called the health industry can offer everything but full-service sex. To operate legally, Japanese health providers offer non-penetrative sexual acts which are deemed to be much lower risk. Sumata is one popular service offered by many Japanese sex workers.
As sumata is meant to mimic penile/vaginal intercourse, when it is offered as a paid service it can be performed in many different positions, just like sex workers offering penetrative sex in other countries. For example, clients may engage in missionary sumata or doggy style sumata.
Although the term sumata originated in the Japanese sex industry, it’s not just professionals that practice it. This activity is a good option for people abstaining from penetrative sex but wanting sexual release.
When someone having sumata thrusts their penis between their partner’s thighs, this practice may be known by the English terms intercrural sex or femoral sex. When the receiving partner stimulates the penis with their labia in sumata, it may be called a pussyjob. The terms outercourse and dry humping are also similar to sumata. However, while the acts are similar, all these terms are not typically used in the adult industry as sumata is.
