Homosexuality
One may say that homosexuality is the term used for people that feel romantically or sexually attracted to their own sex, but other definitions also exist. When one views homosexuality as the term for people that feel romantically or sexually attracted to their own sex, more people are gay than when one might view homosexuality as only a term for people who do have sexual relationships with their own sex. Usually, the term is used to view all the people who are romantically or sexually attracted to their own sex, as well as those with such attractions who have not had a sexual relationship with their own sex yet. Nonetheless, the most visible form of homosexuality is the actual relationship. Most 'evidence' of homosexuality in ancient cultures comes from drawings of the men in an intimate relationship or sex, because it's the most obvious.
