The entire human brain is designed around sex

BBC NEWS | Health | Scans see ‘gay brain differences’

A group of 90 healthy gay and heterosexual adults, men and women, were scanned by the Karolinska Institute scientists to measure the volume of both sides, or hemispheres, of their brain.

When these results were collected, it was found that lesbian women and heterosexual men shared a particular “asymmetry” in their hemisphere size, while heterosexual women and gay men had no difference between the size of the different halves of their brain.

In other words, structurally, at least, gay men were more like heterosexual women, and gay women more like heterosexual men.

First, of course, I would be loth to base anything on a study containing an average 22 and a half members of each group under study. But it really does seem strange to think that the entire design of both hemispheres — visual cortex, language centers, so on and so forth — would be geared toward deciding whom to have sex with. And that all the different modes of sexual interaction — butch vs femme, macho vs. nelly, attraction to tomboys vs glamour queens, studs vs milquetoasts and so on ad infinitum — would be all segment absolutely neatly along the division between penis and vagina.

I guess being bisexual must mean that you constantly feel your brain hemispheres ping-ponging back and forth in size.
