Nice information and descriptions, thanks, but are you meant, men and women haven't much differences about erotic and gaze to opposite sex or you meant about all the issues?
What I gather from the research is that there are different " reward" factors inherent to each sex which are biologically instilled in us to perpetuate the species.
BUT I think a lot of the ways previous studies showed that men were more visually oriented i.e: their brains light up more looking at women then vice versa... now seem to be put to the test. I think there is a different kind of response in women unless you compare them to bridge brain males, but that does not preclude that women are equally reactive and/or responsive.
I find it interesting, as a gay man, since I am not sure whether my brain is hardwired female or male according to these studies. They do tend to entertain and amuse me!
