It's not that Clark is homophobic, he has no problem with gay people and obviously he finds homophobia disgusting, it's just that he isn't gay. Most definitely not. It doesn't fit with how he's imagined his life, getting married to a nice girl some day and settling down with her. No way is he attracted to men.
So he doesn't understand why it upsets him so much to see Bruce flirting with other people, especially when it's men he flirts with. Why he gets downright angry when he finds out Bruce sleeps with men. He doesn't understand why he wants to touch Bruce sometimes. And the closer they become, the more they actually befriend each other, the more time he spends with him, the harder it is to be around him.
And maybe Bruce makes a move one day and Clark doesn't know how to react? Or maybe Clark figures things out on his own? I don't mind how you resolve this, but I would like a happy ending after all the angst and confusion.
