What is "intercourse"?
Ejaculation inside the vagina, also known as internal ejaculation, refers to the situation where a man ejaculates inside his female partner's vagina during unprotected sexual intercourse, and in a broader sense, it also includes ejaculation in the rectum during anal sex.
The term "中出" (zhōngchū) originates from the Japanese word "中出し" (nakadashi), which is composed of "中" (zhōng) (inside) and "出し" (chū) (to release, to ejaculate). It literally translates to "to release inside," meaning ejaculation inside the body.

Creampie
Internal ejaculation, also known as vaginal ejaculation, refers to the act of ejaculating inside the vagina of a female partner during unprotected sexual intercourse, typically upon reaching orgasm. In a broader sense, it also includes ejaculation in the rectum during anal sex. Internal ejaculation is the primary method of achieving fertilization and pregnancy within the vagina. However, due to its potential for unintended pregnancy and the transmission of sexually transmitted infections through semen, it is considered an unsafe sexual practice.
Definitions and Interpretations
When a human male and female engage in vaginal intercourse, ejaculation occurs inside the vagina when the penis reaches orgasm. This is called internal ejaculation; the sperm in the semen will then swim towards the cervix through the vagina. Internal ejaculation can also occur during anal intercourse between human men and women, although the ejaculator is usually the male.

definition
"Internal ejaculation" refers to the act of a man ejaculating semen into his female partner's vagina during unprotected intercourse, or into the rectum during anal sex. Sperm in the semen may travel through the vagina towards the cervix, increasing the chances of pregnancy.

Female pleasure from internal ejaculation
Studies show that some women may feel more comfortable and satisfied when ejaculating inside the vagina, but this varies from person to person and is controversial.
- Feelings and pleasureResearch suggests that approximately 22.61% of women with TP3T reported more intense orgasms when their partners ejaculated inside them, with some experiencing warmth or intimacy.
- Individual differencesNot all women have the same experience; sexual preferences are influenced by physiological and emotional factors.
- Health risksInternal ejaculation may increase the risk of unintended pregnancy and sexually transmitted infections; therefore, it is important to practice safe sex.
Feelings and pleasure
Some women may feel more comfortable, especially experiencing a more intense orgasm, when their partner ejaculates inside them. According to a survey, 22.61% of women reported that their partner's ejaculation during vaginal intercourse made their orgasm more intense, and 17.41% of women believed that the intensity of ejaculation affected their orgasmic experience.
Individual differences and controversies
However, sexual preferences vary from person to person, and not all women prefer internal ejaculation. Studies indicate that 37.91 TP3T women reported that ejaculation volume was irrelevant to orgasm intensity, and 20.91 TP3T women didn't even feel it had any impact. This reflects the highly personalized nature of sexual experience, and some individuals may feel uncomfortable due to concerns about health risks.
culture
This term is commonly used in the adult film industry, particularly influenced by Japan's "chuu-shi" (internal ejaculation) culture in the Chinese context. Similar terms in English include "creampie," which is widely used in subcultures but is often considered sensitive when discussed openly.

Impacts and Risks
Studies suggest that internal ejaculation can lead to unintended pregnancy and the transmission of sexually transmitted infections, such as HIV. Prevention methods include prenatal or postnatal contraception, but these may have side effects. Regulating internal ejaculation in adult films has been discussed in some regions, but no consensus has been reached.
