Cecyl Vise

Just reading the book now and, yes, Cecil comes off as asexual, not at all homosexual.

Freddie thinks, when he finds out Lucy is engaged to marry Cecil, "But at the back of his [Freddie's] brain there lurked a dim mistrust. Cecil praised one too much for being athletic...Cecil made one talk in his way, instead of letting one talk in one's own way...And Cecil was the kind of fellow who would never wear another fellow's cap."

Shortly thereafter, Forster makes Cecil enamored more of ideals than realities; Lucy is for Cecil the romantic ideal of a medieval woman, "like a woman of Leonardo da Vinci's, whom we love not so much for herself as for the things she will not tell us."

And George says (in the novel) to Lucy about Cecil, "You cannot live with Vyse. He's only for an acquaintance. He is for society and cultivated talk. He should know no one intimately, least of all a woman."

So the upshot of all this seems to be that Cecil is of himself and belonging to himself, not capable of being a proper friend or lover.

Edit: How could I have forgotten--Cecil actually asks Lucy if he can kiss her, and in the most awkward way (the asking and the kiss)!
