I think the study may have been flawed in a number of ways. First, sexual attraction is very specific. For instance, if the images had shown 18-year old girls, I would have had little, if any, sexual response. That's just not my thing. On the other hand, if the images had shown middle-aged women, about my age, or plumper women (which is something I'm into), I would have had a strong reaction. Likewise, if it had shown feminine men, I would have had little response.

Now it may be true that for some men, "bisexual" is a cover story, one step out of the closet. But that certainly is not universally true. There are truly men (and women, I'm guessing) who are omni-sexual... extremely sexual beings, who are attracted to both sexes. I know. I'm one of them.

Too many variables have been omitted to give this study true credit.

It is my belief that Bi-sexuality is potentially in everyone male and female for sexual gratification, emotional gratification is not the same nor included in this study.

We live in a sexual stereotypical society, which says men with women and vice-versa, some men fortunately have the chance to think for themselves and have same sex encounters and have received homosexual gratification, luckily some of them men do not deny the heterosexual gratification they experience.

(Is it not strange how men leading heterosexual roles still receive sexual gratification from women and then choose through whatever reason that they are homosexual and then deny the gratification they received while in the heterosexual role? So who are the true liars?)

If our modem society was based on bi-sexual stereotype....then the majority of us would?? BI SEXUAL

With the odd outcast preferring, heterosexual or homosexual lifestyles or course!

Yes I am studying psychology and yes I am Bi-Sexual.

More in depth criticism from Mixing Memory here and here.

"In terms of the bisexuality study it's an interesting one. I suspect it's partly in the methodology. It's kind of muddled. They seemed to show people straight porn and gay porn, but expected the bi oriented guys to like both equally and seemed surprised when they weren't?

"Some bi guys like mixed scenes (e.g. a guy and a woman together), some identify with either male and male or male/female experiences. I think the whole issue about defining sexuality gets messy when we have to fit people into categories. People can cope with gay or straight, it seems, but can't fit 'bi' into one box ('scuse the pun).

"My take, as usual, would be on the method - I don't feel these lab based studies using erotica are very reliable. The people behind the research never seem to reveal how they selected the erotic material to be shown, and frankly watching porn in a lab isn't representative of how you'd enjoy it elsewhere. It's also someone else's choice of 'erotic' which (as anyone knows if they've stumbled on someone else's porn collection) is usually a bit hit and miss arousal wise."

Although she does temper her criticism by saying:

"However, I could be being very unfair about these researchers since I've not read their original study."
