Homosexuality in "The Wars"

Homosexuality seems to be something that appears quite a bit in the novel “The Wars”, written by the Canadian author Timothy Findley.  For example, after retiring to his room from a bath in a former mental institution, Robert Ross is violently raped by thirteen men, who we can assume are all gay. Near the start of the novel, when Robert Ross and some of his soldier friends are visiting a whore house, and Robert is in a room with a prostitute, via a hole in one of walls in the room, Robert is able to see celebrated war hero Eugene Taffler making love to a large male. Perhaps this recurrence of homosexuality in this novel is due to the fact that Timothy Findley, the author of “The Wars”, is homosexual. This is what I thought to be true at first after reading this novel, and which later turned out to be actually true.
