Maecenas faucibus mollis interdum. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Sed posuere consectetur est at lobortis.

Sexual health requires a positive and respectful approach to sexuality and sexual relationships, as well as the possibility of having pleasurable and safe sexual experiences free of coercion, discrimination, and violence. For sexual health to be attained and maintained, “the sexual rights of all persons must be respected, protected, and fulfilled”

Wellbeing is a state of physical, emotional, mental, and social well-being in relation to sexuality; it is not merely the absence of disease, dysfunction, or infirmity.

Affirming sexual needs without shame and judgment is key to making sex education accessible and equitable providing access (ACOG, Ford, Satcher). Cultural and personal variation in sexual practices should be valued (ACOG).

That’s why we look to the science of sex to guide our principles, while understanding that not enough high quality, evidence-based research has been done for vast areas of human sexuality.
