I don't think you can read homosexuality into "Follow me Home". It certainly deals with love between men, but Kipling did not have the erotic kind of love in mind when he wrote that poem. I think he wanted to write about comradeship, particularly between soldiers who have (presumably, since this isn't dealt with in the poem) seen active service together, and the grief that the soldiers he knew felt on the untimely death of a friend. "Ford o' Kabul River" has a similar theme.

Kipling was no prude, but I think this was one taboo that he didn't touch. Perhaps the Kipling scholars can prove me wrong.
