Lube 101 Definitions

Disodium EDTA

Disodium EDTA is a common preservative used in many industries including medical and commercial.  Disodium EDTA is found in many of the most popular sexual lubes and creams to keep a longer than usual shelf life.

Damiana Leaf

Damiana leaves is a shrub or plant used by Mayans and other native people of Mexico to boose sexual potency.  Damiana leaves are known to be used as an aphrodisiac and sexual attractant.  This shrub has been used in lubricants, gels, creams, and even perfumes to boost sexual attraction.

 

Double Penetration

A sexual act in which the anus and vagina are penetrated simultaneously.

While “double penetration” is commonly used to describe group sex, the term can also refer to the use of toys or fingers during solo play or sex with a single partner. As is the case with all types of anal play, it is important to choose safe toys with flared bases when enjoying double penetration and to use appropriate lubrication. Anal toys should not be used vaginally, as this can cause infections.

Domination/Dom

In BDSM and roleplay, domination refers to the act of exercising control over a submissive partner (often referred to as the “sub”).

The dominating partner (or “dom”) may take control in a variety of ways, and doms and subs will sometimes switch roles. Many couples create a safe word or take other steps to clearly set limits before engaging in any role playing; see “Submission/Submissive/Sub” for more information.

Dildo

A toy used to penetrate the vagina, or anus for the purpose of sexual pleasure.

One of the oldest types of sex toy, dildos are available in thousands of shapes, sizes, and designs. Many use lifelike textures for added sensation. Common materials include silicone, ABS plastic, glass, cyberskin, and even steel.

There is some confusion and overlap between the terms “dildo” and “vibrator;” while “dildo” can refer to any phallic device used for sex or masturbation, it generally refers to toys that do not have a vibrating motor.

Dry Sex

Intercourse that occurs without lubrication of any kind. “Dry sex” typically refers to vaginal intercourse, but the term can refer to any sex act.

Lubrication protects sensitive skin from friction, and dry sex can be painful and potentially dangerous. Dry sex is associated with increased risks of many different types of sexually transmitted infections.

Additionally, the act of removing vaginal lubrication alters the vaginal flora, increasing the risks of some health issues including bacterial vaginitis.

Douche

A device that propels water or another liquid into the vagina to remove offensive odors. Most douches consist of a rubber or plastic bulb (commonly referred to as the “douche bag”) and a soft-tipped nozzle.

Douching is not medically recommended by most physicians, as it upsets the natural balance of the vaginal flora. It can increase a woman’s risk of contracting certain health problems including bacterial vaginitis and some sexually transmitted infections. There is some evidence that douching can also cause fertility issues.

While douching is sometimes used after sex as a form of contraceptive, it is not effective for this purpose.

Depo-Provera

A type of hormonal contraceptive, administered once every twelve weeks via an injection. Depo-Provera contains a substance similar to progesterone, a female sex hormone. It prevents eggs from implanting in the uterus, thereby preventing pregnancy.

While Depo-Provera is 99 percent effective as a contraceptive, it does not offer any protection against sexually transmitted infections. It can cause some side effects including vaginal dryness and menstrual cycle irregularities.

It is completely reversible – if a woman stops receiving Depo-Provera treatments, she can safely carry out a normal pregnancy within about 14 weeks of her last injection.

Damianav

An extract made from turnera diffusa, a common North American shrub. Damiana is used in some lubricants as a libido (sex drive) enhancer; see “turnera diffusa” for more information.
