This type of oral sex involves the exchange of blood and semen. Some people consider this a kink, but it’s best not shared with someone who’s not properly STD-tested.

Definition

A rainbow kiss is a sex act that involves swapping semen for blood between consenting adults who share a bodily fluids fetish. It’s a “higher level” of penetrative sex that’s usually performed during one partner’s period, says Dr. Wendasha Jenkins Hall, PhD, an Atlanta-based sex educator.

This type of sex is considered taboo to many, but people who have certain kinks find it arousing. It’s typically performed in the 69 position, where one person licks blood off of a manstruating woman’s vagina while the other performs oral sex on her.

As with any type of unprotected sex, rainbow kisses have infection transfer risks that could lead to HIV, hepatitis, gonorrhoea, herpes, and other s*xually transmitted diseases. It’s also not recommended for women who are pregnant or breastfeeding, as the blood from the menstruating woman’s body could contain fetal cells that can cause birth defects.

Origin

The term rainbow kiss may sound like the latest makeup trend, or perhaps the name of a sweetened cocktail. But it actually refers to a sexual act that involves mixing menstrual blood and semen.

The act typically begins with one person lying on their back, their genitals positioned next to their partner’s mouth for oral sex. It can also be done while both people are in the 69 position, which is the easiest way to perform the sex.

Wendasha Jenkins Hall, PhD, an Atlanta-based sex educator and founder of The Sensible Sexpert, says rainbow kisses fit on the broader spectrum of bodily fluid kinks and fetishes. It’s a bit more elevated than penetrative sex that occurs during menstruation, she adds.

But any sex act that involves swapping body fluids between partners should be done safely, and rainbow kisses are no exception to this rule. You’ll want to make sure that you and your partner are aware of STIs that can be transmitted through the exchange of semen and period blood, including HIV, syphilis, and gonorrhoea.

Meaning

A rainbow kiss is a sexual act that involves the exchange of menstrual blood and semen, usually performed by consenting adults who share some sort of fetish for bodily fluids. It’s a form of “snowballing”—the practice of exchanging bodily fluids from one partner to the other—with a bit of a twist, according to Dr. Wendasha Jenkins Hall, PhD, sex educator and founder of The Sensible Sexpert.

A common variation of the rainbow kiss is when a man ejaculates in a woman’s mouth while she’s on her period, allowing the two to mix blood and semen to create a beautiful rainbow color. It’s typically done in the 69 position, where one partner is on their back and straddles the other, with their genitals in line with each others’ mouths.

While this act may seem like a fun way to express passion, it’s important to note that rainbow kisses can be dangerous if performed incorrectly. The exchange of both blood and sex can transmit various diseases, including HIV, hepatitis C, and syphilis.

Significance

The term “rainbow kiss” may conjure up images of xx, 1st base, or Australian kisses (or chumma and bloody mary), but it actually refers to a sex act that’s a little edgy for the average person. This is because a rainbow kiss involves the exchange of bodily fluids between partners, specifically menstrual blood and semen.

A rainbow kiss is a heteronormative sexual activity, according to urban dictionary, and is typically shared by males and females. It occurs when one partner performs cunnilingus on a woman and then orally swaps her sperm with her blood.

It’s important to know that blood can transmit infectious pathogens, which can lead to s*xually transmitted diseases like HIV and hepatitis. To protect yourself, Hall suggests knowing your partner’s s*xual status and being careful when swapping blood.
