Lesbians respond differently than heterosexual women to bodily smells, according to a Swedish study. Twelve lesbians and twelve straight women inhaled air mixed with hormones -- one batch derived from male sweat, the other from the urine or pregnant women -- and PET scans on the area of their brains "though to process sexual cues" were examined. Only the straight women's brains lit up during the test.
A year ago, an eariler study by the same team ran the same tests on straight and gay men, with gay men having the same response to male sweat as straight women.
