I feel like the basic premise of this study is far too complicated, because of traditionally far too static classifications. People have never and will never be strictly heterosexual or strictly homosexual. They have a preference, but they are never going to find the other sex entirely unattractive, even if some people would want to do your head in for claiming otherwise. Ultimately, a butt is a butt, a nipple is a nipple and a man boob isn't that different from a woman boob either. Certain characteristics like fitness, charisma, nurturance, intelligence, loyalty etc. can be viewed as sexy, too, and are entirely decoupled from sex. As such, when you identify as heterosexual, you have a preference for the opposite sex, which is high enough that you wouldn't consider both sexes generally equal like with bisexuality, but it does not mean that you cannot find anyone of the same sex sexy, too. They could have lots of characteristics that are typically ascribed to the other sex. Or they just happen to have the right combination of characteristics, apart from the sex, that you find really attractive. You would prefer for them to be the opposite sex, but you would also prefer for that opposite-sex-person that's into you to be a top model. At some point, you just stop holding your breath and bang what's available.
