Dean + the scientific theory of Sexual Fluidity
It's funny how this movie--which I've liked since it came out--can be so chock-full of cinematic cliches and stereotypical romantic comedy (and gay)themes and yet still also have a bunch of interesting, atypical things about it.
One of the interesting things is the reversals of some common queer themes. For instance, instead of the struggling queer character pushing themselves to feel something (either romantic or sexual or both) for a member of the "other" sex, you have the opposite: an apparently heterosexual character (more on that below), Dean, who struggles to try to make himself feel a sexual attraction to a special man (Henry) in his life.
A lot of you have questioned whether Dean was really Gay or Straight (unsurprisingly and regrettably, most ignore the concept of male bisexuality). I argue that some of the recent research on sexual orientation might help explain the turmoil Dean seems to be going through. I'm speaking specifically of the theories of Lisa Diamond, the prominent researcher behind the theory of Sexual Fluidity. However, Diamond focuses on women, precisely because, due to women's less-consistent distribution of sex hormones as compared to men, sexual fluidity appears much more common among women than men. (Sexual fluidity in women is more likely to occur when a woman's sex hormones are at a low ebb during certain points in her cycle).
But in addition to those biological factors, I think the different socialization of men and women is also a factor in sexual fluidity being less apparent among men. In any case, even if it's not common among men in a statistical sense, fluidity's still a possibility for at least some men. I think Dean's one of the many men who *doesn't* display a capacity for sexual fluidity, and this explains his tormented behavior in BIG EDEN.
Briefly put: I think that Dean was a heterosexually-oriented character who fell in love with/had a romantically-tinged love for Henry. (Contrary to pop/folk belief, sexual desire is NOT the same thing as romantic affinity; the two are separate things governed by separate parts of the brain, and it's quite possible to feel one but not the other for someone). Although such a thing as "sexual fluidity" exists (i.e. certain triggers causing you to feel sexual desire for the "wrong" sex for your orientation), Dean--like many men--- just doesn't have a high capacity for fluidity. Here, Dean fell in love with Henry, but never experienced an episode of "sexual fluidity" toward him.
Such was the basis of Dean's turmoil in the movie: he LOVED Henry, wanted to be in non-sexual but loving physical contact with Henry (i.e. all those times he danced with Henry, roughhoused with him, swam with him, hugged him, and even picked him up and dragged him around)---but, he just couldn't SEXUALLY DESIRE Henry. The reason he couldn't sexually desire Henry was twofold: (1) first, he had a Heterosexual orientation, and (2) his Heterosexual orientation could not be overcome by an episode of Sexual Fluidity.
When you put those two things together, it makes for great turmoil in the person (here, Dean) who doesn't understand how it is that he can feel such strong, warm, enveloping feelings towards someone, yet not be able to feel a spark of sexual interest in them. The romantic interest does not align with the sexual one, and the dissonance is painful, especially in a culture in which we're taught that romantic love and sexual desire are inseparable parts of the same package.
Dean's behavior seems very consistent with the old 19th/early 20th century idea of a "smash" (as opposed to a crush). Smashes were the nickname given to the same-sex romantic yearnings that often appeared between (heterosexually-oriented) girls in all-girls schools. The girls would develop fixations on one another that went beyond the usual close friendships; they would want to look into the eyes of the person they were "smashing" on, hold their hand, lie next to them, and sometimes even (non-erotically) kiss them.
While in some people, a smash is the trigger that causes Sexual Fluidity to ignite and makes someone able to sexually desire "the wrong sex" for them, in others, their low capacity for Fluidity means the smash never gives rise to sexual desires. The romantic fixation remains purely that--a romantic, not erotic, fixation.
Smashes of the latter sort--i.e. the type that never trigger sexual fluidity---have been observed and recorded among the young men in many different cultures and eras--from ancient Greece to indigenous tribes in contemporary Africa. These men are friends who have a strong loving attachment to one another--perhaps even an emotionally passionate and physically affectionate one like Dean's in BIG EDEN-- yet their proactive sexual desires fuel them to seek out women, not their beloved male companion, for sexual gratification.
I think this not only explains Dean's tortured and "muddled" (as many of you here have put it) behavior, but it further explains how it is that he's linked with the nondescript blonde woman towards the end of the movie. My guess is that his heart still belongs to Henry, but that, like most men, he instinctively privileges his sexual orientation over his non-erotic emotional attachment.
Interestingly, many women--whether due to socialization or to biological traits or both--do the opposite: they privilege their emotional connections over their proactive sexual desires/sexual orientation.
Anyway, I first saw this movie in 2001, several years before all of this research on orientation and fluidity came to light. I enjoyed it then despite some of the awful acting, and yes, despite the muddled Dean situation. The filmmakers managed to convey enough of the main point: that Dean loved Henry in a special way--a way perhaps more than is usual between friends, especially male ones---but that love just wasn't enough to overcome his inability to sexually desire Henry.
The scientific theories just add a further layer of plausibility to a situation that many have automatically rejected as outlandish. There are tons of improbable and implausible things about BIG EDEN, but the complex relationship between Henry and Dean is not, IMO, one of them.
