I think I first saw Steve Zahn in SubUrbia, as one of a group of disillusioned teens in the bleak urban wastelands of the 1990s. I didn't live in a bleak urban wasteland, and there were no gay characters, so I couldn't relate.
Next came The Object of My Affection (1998), which I didn't see because it seemed homophobic: a gay guy changes to straight.
I thought Saving Silverman (2001) was homophobic, too, about a lesbian who changes to straight. (That appears to be another movie).
Ok, I haven't seen many of Steve Zahn's movies, but I remember him from Friends: he plays Phoebe's husband, whom she married because he was gay, and it's cool to have a gay husband? Except he decides that he's not gay after all. That sounds homophobic, too.
Heck with it, let's just look at some nude pics. There are some frontal and rear pics on Righteous Gemstones Beefcake and Boyfriends.
