So I thought he was gay ?

Lol. The movie is deeper than that. The point of that scene is to show us that he's so desperate for sex, he's willing to get his dick sucked by a guy just to get off. He's disgusted by what he's doing in that scene.

I don't know why people insist on creating their own interpretations of a story when the given details are so plainly obvious. Maybe this is a troll's bait thread. I don't know. The film's ambiguous ending provides more room for open pondering and imagination (does Brandon decide to follow the subway train lady or not?).

I think it's quite clear that Brandon was heterosexual. With the exception of that one instance in the gay club/bar, his desire and fantasies were centered on women. If he were gay, he'd be calling up male hookers, buying gay porn mags, visiting gay porn internet sites, hitting on guys at work or out in public (if he were bisexual, there would be a mix of male and female targets). Did you see him routinely doing any of that in the film? No. The whole point of Brandon entering the gay bar, as someone already mentioned, was to show the depths of his addiction. He was so broken and desperate that he crossed a line that he normally wouldn't. As a heterosexual man, receiving oral sex from a random male he had just seen on the street was a low point for him. He was not enjoying it. To be honest, Brandon wasn't enjoying ANY of the sexual encounters he had during his sex binge (or any other time before then). The only occasion where sexual pleasure combined with emotional attachment seemed attainable for him was with Marianne (and we all know how that frustratingly ended).

Funny how people determine a person's sexual orientation based on ONE sexual act. Determining human sexuality is more complex than figuring out whether a person screws a male or female (or both). Physical attraction, sexual fantasies and self-identification play as much a part in classifying sexual identity as choice of sexual partner. It's a fact: people do sexually experiment. What I find interesting is when a man who consistently has sex with women suddenly sleeps with another male (only once!), he is automatically deemed gay. When a homosexual man who consistently has sex with men suddenly sleeps with a woman (only once!), he's NOT immediately viewed as being straight (perhaps seen as being confused, drunk, or under duress to conform to hetero norms).

I thought for a second it had been the point of the whole movie, but after I watched the threesome scene and what followed afterwards it was obvious the bj seen was meant to show the intensity of his addiction and how far he was willing to go just for pleasure.

I'm glad he wasn't gay, because if that was the point of the movie, I would think the film would be shallow.

It shows he's bi not gay. lol.

Not all details are clear about what causes the compulsions in Brandon. Sex addiction/obsession/compulsion also does not happen in a vacuum. While I am not a proponent of the idea, I believe that an interpretation that Brandon was actually a bisexual man repressing his desire for men does make sense as a possible interpretation, as does the incest angle. I don't understand why people get so deffensive about the fact that Brandon could possibly be a queer man. It has hapened to a few bisexual men I know (I am bisexual myself, but luckily did not struggle with my queer attraction this way). Some bisexuals concentrate in the accepted sexual attraction so much that they used to cover up and repress their queer attraction.

Some proponents of this theory believe that Brandon and his boss are attracted to each other, which explains why the boss let slide the porn-at-the-office issue so easily.

Again, the film is open to interpretation as far as what causes the compulsion for sex. For some it is incest, for some it is trauma, for others queer desire, or it could be a combination of them all.

By the way, I believe sex addiction (or at least sex obsession) does exist. I survived a relationship with someone who had it in tandem with Narcissistic personality disorder. Not fun.

Thats why only after getting bj from a guy he was ready to make peace with his sister and in the end he didnt get up after the woman because he was done trying to cover it.>>>

My thoughts exactly...it is left for us, the viewers to wonder ..."did he, or didn't he get up after her.."
