I've been watching Guy Maddin's 2007 My Winnipeg and there's a sentence there I have difficulty understanding. The narrator is talking about the coldest month, January, and it goes something like this:
The deepest part of the winter. No end in sight. The condoms come off. These are the bareback months of Winnipeg. Your breath freezes in front of your face and falls to your feet with a tinkle.
I assume the first sentence refers to the idea that when it's cold penises tend to "shrink" (or is it just me?). But what does the "bareback month" mean here?
