There is an odd double-standard when it comes to men. We assume every woman is only a stiff drink and a stiff breeze away from bisexuality, but most hetero males cannot imagine being with another man. While I've never had the pleasure, I can certainly recognize that some men are particularly good looking, and some are funny, and some are smart. That said, looks alone, save in extraordinary circumstances, would never get me into bed with a guy. There would have to be some really exceptional rapport and (dare a red-blooded man admit this?) trust before I'd even consider it. The thing is, I know men. I'm one of them. And we will say anything to improve our chances of getting laid. Forget diseases or exclusivity, in order to open myself up, to be vulnerable in that way would require the alignment of many stars, a blue moon, a full double rainbow, and free add-ons at the yogurt bar. I can't speak for everyone, but hetero men are conditioned...heavily to perceive themselves as the invaders, the penetrators, and the violators. To consider sharing dominance, to become the other is alien, disconcerting, and dangerous. Naturally, we hide these worries behind machismo, testosterone, and beer. But I argue that fear of intimacy is the biggest hurdle most straight guys face, because it would take such a high level of trust to overcome their conditioning.
