What is a dam?

A dam is a stretchable latex rectangle used to provide protection from sexually transmitted infections during oral sex.

How does a dam work?

A dam allows oral stimulation of the anus or female genitals without direct physical contact or sharing of body fluids. The dam is placed over a woman’s genital area before her partner performs oral sex on her, the dam acts as a barrier between her partner’s mouth and her genitals. They can also be used by men or women while “rimming”, which is oral sex performed on a partners’ anus, providing a barrier between the partner’s mouth and the anus. Water based lubricant should be applied to the genital area or anus prior to using the dam. Using a dam for oral sex helps to prevent the spread of sexually transmitted infections.
