Homophobia means an aversion to touch persons of the same sex (beyond handshake) or to see them naked. In many societies, this is expected from males, possibly hoped to prevent homosexuality. In other societies including some "hippie" communities in the 1970s, it was or is criticized - with no connection to homosexuality altogether.

Women, on the other hand, are often expected to embrace and kiss each other. Not long ago, many men believed that there is no such thing as female homosexuality at all. When someone caught his wife naked in bed with his neigbour's wife, he may well have found it cute.

However, homophobic women also exist, in various forms.

As McGrath mentioned, the word is sometimes falsely, wrongly, erroneously, and mistakenly used for aversion to homosexuals. This usage seems to have arisen only in the current century, but is embraced by many activists including Wikipedia authors in various languages.
