I used to wonder why going into the locker room at the local university when we had high school tournaments there confused me. It smelled musty and dank cuz it was an old building yet with the unmistakeable smell of MAN. It just turned me on somehow in some weird way i did not understand at the time.

I came upon this study that demonstrates there is a deep brain connection that men who are attracted to men have that straight men do not. Importantly it CANNOT Be accounted for by anything other than the way the brain itself works and is NOT an acquired thing. NO CHOICE NOT LEARNED.

FROM the US National Academy of Science:
Jan-Åke Gustafsson, Karolinska Institutet, Stockholm, Sweden,

Cerebral responses to putative pheromones and objects of sexual attraction were recently found to differ between homo- and heterosexual subjects. Although this observation may merely mirror perceptional differences, it raises the intriguing question as to whether certain sexually dimorphic features in the brain may differ between individuals of the same sex but different sexual orientation. We addressed this issue by studying hemispheric asymmetry and functional connectivity, two parameters that in previous publications have shown specific sex differences. Ninety subjects [25 heterosexual men (HeM) and women (HeW), and 20 homosexual men (HoM) and women (HoW)] were investigated with magnetic resonance volumetry of cerebral and cerebellar hemispheres. Fifty of them also participated in PET measurements of cerebral blood flow, used for analyses of functional connections from the right and left amygdalae. HeM and HoW showed a rightward cerebral asymmetry, whereas volumes of the cerebral hemispheres were symmetrical in HoM and HeW. No cerebellar asymmetries were found. Homosexual subjects also showed sex-atypical amygdala connections. In HoM, as in HeW, the connections were more widespread from the left amygdala; in HoW and HeM, on the other hand, from the right amygdala. Furthermore, in HoM and HeW the connections were primarily displayed with the contralateral amygdala and the anterior cingulate, in HeM and HoW with the caudate, putamen, and the prefrontal cortex. The present study shows sex-atypical cerebral asymmetry and functional connections in homosexual subjects. The results cannot be primarily ascribed to learned effects, and they suggest a linkage to neurobiological entities.

I now know why i hate deodorant and cologne, it blocks my brain.

I think thats why i could have and enjoy straight sex, but it never triggered the deep centre of my brain. It was all, perfume and Hi karate'

Thanks, 1lifenow. Studies like these really make the blanket "sexual orientation is a choice" argument increasingly tougher to make. I don't think you can choose to have a different brain structure that's wired to interpret stimuli differently.

For those interested in the study title, it's "PET and MRI show differences in cerebral asymmetry and functional connectivity between homo- and heterosexual subjects" and it's actually by Ivanka Savic and Per Lindström of the Stockholm Brain Institute, Department of Clinical Neuroscience, Karolinska Institute, 171 76 Stockholm, Sweden (The names above are the editors of the study for publication). You can find the full study text and data here.
