Here’s an interesting discussion on forecasting sexual orientation:

We all know the stereotypes: an unusually light, delicate, effeminate air in a little boy’s step, often coupled with solitary bookishness, or a limp wrist, an interest in dolls, makeup, princesses, dresses and a staunch distaste for rough play with other boys; in little girls, there is the outwardly boyish stance, perhaps a penchant for tools, a lumbering gait, a square-jawed readiness for physical tussles with boys, an aversion to all the perfumed, delicate, laced trappings of femininity.

I’m sure that my parents thought, or at least worried, that I was going to be homosexual. I was a bookworm, and didn’t enjoy roughhousing or sports. On the other hand, I never had an interest in girlish things, and was more into pirates and cowboys. In any event, I’ve never had the slightest interest in the same sex, sexually speaking — I’m as heterosexual as they come (so to speak). But I think you have to be in abject denial to think that sexual orientation is a “choice.” The only people for whom that’s the case are bisexuals.
