This New York Times piece by Jane Gross looks at gay man who marry women and have furtive relationships with men on the side:
They spend decades denying their sexual confusion to themselves and others. They generally limit their encounters with men to anonymous one-night stands and tell all manner of lies if their wives suspect.
What's interesting is that, as Gross points out:
…so-called "Brokeback" marriages have hardly disappeared, as many experts assumed they would, even in an age when gay couples, in certain parts of the country, live openly and raise children just like any family.
Internalized homophobia, guilt, and fear of life outside the culturally enshrined heterosexual norm are still potent forces.
Another article of interest, from the London Times, looks at sexual fluidity. Matther Parris argues that sexuality often doesn't fit neatly into the categories of "gay" and "straight":
I think a substantial preponderance of men are more heterosexual than homosexual, but scattered fairly evenly between 100 per cent and half-and-half; and that the smaller number who think of ourselves as gay are likewise quite evenly distributed along the spectrum from the halfway point.
That's seems a bit too fluid to me, and I think Kinsey was probably right that toward the ends of the spectrum sexual orientation is pretty well fixed and in no sense a "choice." Still, Parris may be right when he notes:
... we who call ourselves gay know well that most men who call themselves "bisexual" are more gay than straight, but afraid or unwilling to say so. But what we overlook is that for every gay posing as a bisexual, there are probably a dozen bisexuals posing as straight.
And in a better world, of course, all that posing wouldn't be necessary because (among consenting adults) who you love and how you build a life together just wouldn't make any difference.
