I think I read about that same study in Sex Before Dawn. It also found that women had increased blood flow and wetness when viewing any sexual act from things they claimed interest in, to no interest in, and even to those they claimed disgusted them. It was suggested to be somewhat of an auto injury prevention attempt in the case of rape. If that is the case then it wouldn't necessarily indicate women are more likely to be bi.
