Stands for Ultra Realistic 3.0, a trademarked sex toy material with a soft, lifelike feel. UR3 is a type of thermoplastic elastomer (TPE) that does not contain any phthalates. It is hypoallergenic and considered suitable for people with skin sensitivities.

UR3 can be cleaned with sex toy cleaners or with warm water and a very mild soap. Because it is porous, it is very important to clean it after every use. UR3 toys often ship with a “renewal” powder, which is commercially available; this powder helps the toy to retain its soft, hyper-realistic feel. Users should store UR3 toys in plastic bags or in dedicated storage cases to reduce the chances of microbial growth.

UR3 is commonly used for male sex toys. It is compatible with water-based lubricants, but silicone- and oil-based lubricants can permanently damage the material.


Located above the vaginal opening in women and in the penis in men, the urethra is the tube connecting the genitals to the urinary bladder. Humans urinate through their urethras, and men ejaculate semen and sperm through this opening

Urinary Tract Infection (UTI)

Commonly abbreviated as UTI, a urinary tract infection is a localized infection that affects the bladder, kidneys or another part of the urinary tract. The infection often causes pain and discomfort, and treatment typically involves a course of antibiotics. Women are generally much more susceptible to urinary tract infections than men, but UTIs are relatively common in both sexes.

To avoid infections, a person can maintain a healthy diet, urinate 15-20 minutes after intercourse, avoid unprotected sex, and use appropriately pH-balanced lubricants.






A flowering plant (scientific name: tribulus terrestris) commonly used to as a supplement to improve sexual function. Some personal lubricants incorporate a tribulus extract to promote erections in men and sexual receptivity in women.

While some product manufacturers claim that tribulus can increase testosterone levels, there is limited scientific evidence to support this claim. However, some studies have shown a correlation between tribulus supplementation and enhanced sexual performance in animals.
