Gynephilia (or gynophilia) (From Greek gunē, "women," -philia, "love") is the romantic and/or sexual attraction to adult females, and its counterpart androphilia (from Greek andro-, "male," + -philia, "love") is attraction to adult males. There are two main reasons why these terms have been used: to describe either the age or the sex/gender of the object of an individual's sexual orientation.
