No it doesn't, I believe I know the study you are referring to. The study was conducted on a group of homophobic men as the test subjects, another group of men (these ones more accepting of homosexuality) being the control variable.
The study involved playing homoerotic material to the homophobic men, and recording their penile function and flow of blood, as well as heart rate etc. It showed a higher likelihood that men with homophobic tendencies are more likely to get an erection and increased blood circulation from viewing homoerotic material, but that this may also be attributed to the natural response of the body to aggressive stimulus.
That being said, I seem to recall something about decreased penile function when adrenalin is pumped into the body - but who knows.
If that isn't the study you were referring to, I would love a reference/link to the study
