There is a lot of talk about Bromances these days. The urban dictionary definition of a bromance is described as "complicated love and affection shared by two straight males." But what if the two men decide to have sex? Does that make them gay or bisexual?
When girls do this in
Girls Gone Wild they are not accused of being latent lesbians or bisexuals. Their sexual orientation is not speculated about at all as it turns out. But this is different for me.
Understanding Straight Men Who Have Sex with Men
There's growing evidence that many men who have sex with men aren't all gay or bisexual. According to the Centers for Disease Control, more than 3 million men who self-identify as straight secretly have sex with other men-putting their wives or girlfriends at risk for HIV infection and other sexually transmitted diseases.
A recent New York City survey that appeared in the September 19, 2006, issue of the Annals of Internal Medicine found that nearly 1 in 10 men say they're straight and have occasional sex with men. In addition, 70 percent of these men are heterosexually married. In fact, 10 percent of all married men in this survey reported engaging in same-sex behavior during the previous year.
To best understand these men, therapists and clients need to be able to differentiate four terms that are often confused: sexual identity and orientation; sexual preferences; sexual fantasies; and sexual behavior. Contrary to common usage, they aren't always in alignment.
Sexual identity and orientation encompasses one's sexual and romantic identity, in which thoughts, fantasies, and behaviors work together in concert. It's the alignment of affectional, romantic, psychological, spiritual, and sexual feelings and desires for those of the same or opposite gender. Sexual orientation doesn't change over time. One's sexual behaviors and preferences might change, but like one's temperament, one's orientation remains mostly stable. The term also refers to how someone self-identifies, not how others may categorize him or her. Some people self-identify as straight, while others self-identify as gay or lesbian, bisexual, or questioning. It's important as therapists to ask your clients how they self-identify, regardless of with whom they have sex.
Sexual preferences refer to sexual acts, positions, and erotic scenarios that someone prefers to have while engaging in sexual activity. The term takes into account what individuals like to do and get into sexually, not necessarily with whom they like to do it. Preferences and erotic interests can change over time, as one becomes more open or closed to certain thoughts and behaviors.
Sexual fantasies are any thoughts that one finds arousing. They can encompass anything-sexual positions, romantic encounters, body parts, clothing and shoe fetishes, even rape. Sexual fantasies aren't necessarily acted out. In fact, in many cases, they aren't.
Sexual behavior is any behavior intended to pleasure oneself and/or one's sexual partner. It doesn't necessarily reflect one's orientation. For example, men who are imprisoned engage in sexual behaviors with other men, but do so out of sexual necessity, not because of erotic interest in another man. They desire the behavior and the sexual release it achieves, and the gender of the partner is secondary.
For straight men who have sex with men, same-sex encounters aren't about romance or sexual attraction and desire, but about sexual and physiological arousal-"getting off" with another who's male and accessible. They don't sexually desire or get aroused by looking at other men, only by the sexual act. But if they don't actively desire other men, how do they get to the point of having sex with them? These men typically want to bond with and get affection from other men. Their behavior may reflect a desire to experiment, to engage in something that's taboo, or to express inner psychological conflicts involving their sexual feelings and desires that have nothing to do with having a gay or bisexual identity.
Straight men who have sex with men do so for a variety of reasons. Some have been sexually abused and are compulsively reenacting childhood sexual trauma by male perpetrators; some find sexual release with another man more accessible; some have sex with men because it's easier and requires fewer social skills than those required to have sex with women; some are "gay for pay" and get financial rewards; some like the attention they receive from other men; some like anal sex, which they're otherwise too ashamed to talk about or engage in with their female partners.
When I learn that a straight client is having sex with men, I ask a series of questions: What is your interest in men? Do you prefer one type over another? Do you feel drawn and compelled to satisfy your sexual urges with men? Do you care about the physical appearance of the man? Do women play any role in the fantasy? Is it different for you if they aren't? I also try to listen for the themes running through their sexual interests and fantasies, which often decode aspects of their personal identity and histories.

I think there's a certain irony to an argument where the openly, proudly-labeled gay guy is trying to force someone to fit within his own definitions of sexuality. That's not what we, as a community, should aspire to do. While I tend to agree with about 99.997% of what Jacero has said in his very well-written, thoughtful postings, my problem with the other .003% is that I believe that he, too, is lending credence to the fallacy that all sexual behavior either can, or should be defined.
