If you have an academic login I can post the studies.

Its actually interesting because they were VERY hesitant to release the data (sample was only about 100 people) but oddly not as many people want to take the political risk to co firm or refuete the conclusions. (Especially since it showed heterosexual females lacked the same sex response found in all men AND homosexual females. They blamed it on the possible insensitivity of the female junk measuring devices. Or speculated that heterosexual females have a distinctly different and unkniwn genital reaction to sexual excitement)
