Latent homosexuality is an erotic inclination toward members of the same sex that is not consciously experienced or expressed in overt action. This may mean a hidden inclination or potential for interest in homosexual relationships, which is either suppressed or not recognized, and which has not yet been explored, or may never be explored.
The term was originally proposed by Sigmund Freud. Some argue that the latent homosexuality is a potentially iatrogenic effect (that is, it is not present until suggested by a therapist). Others argue that the term latent is not truly applicable in the case of homosexual urges, since they are often not in the unconscious or unexpressed category, but rather exist in the conscious mind and are (often violently) repressed on a conscious level.
A theory that homophobia is a result of latent homosexuality was put forth in the late 20th century. A 1996 study conducted at the University of Georgia by Henry Adams, Lester Wright Jr., and Bethany Lohr indicates that a number of homophobic males exhibit latent homosexuality. The research was done on 64 heterosexual men, 35 of whom exhibited homophobic traits and 29 who did not. They were assigned to groups on the basis of their scores on the Index of Homophobia (W. W. Hudson & W. A. Ricketts, 1980). The groups did not differ in aggression.
Three tests were conducted using penile plethysmography. While there was no difference in response when the men were exposed to heterosexual and lesbian pornography, there was a major difference in response when the men were exposed to male homosexual pornography.
The researchers reported that 24% of the non-homophobic men showed some degree of tumescence in response to the male homosexual video, compared to 54% of the subjects who scored high on the homophobia scale. In addition, 66% of the non-homophobic group showed no significant increases in tumescence after this video, but only 20% of the homophobic men failed to display any arousal. Additionally, when the participants rated their degree of sexual arousal later, the homophobic men significantly underestimated their degree of arousal by the male homosexual video.
