Homosexuality is considered to be same-sex sexual attraction and behavior and 'gay' is a synonym of homosexuality. While 'gay' can be thought of as a synonym to 'homosexual,' there is more to the meaning of gay than that. The term 'gay' may be confusing and even foreign to some, forcing people to ask, 'What is gay?' or ' Am I Gay?' And while some might think the definition of 'gay' is simple, to many, it actually isn't.
