How exactly is Cal hurt to bleeding? SPOILERS
...in the last twenty minutes or so. I just wasn't clear about that. Jonno rapes him once, though Cal is (as we've seen in an anonymous encounter) no penetrative virgin at that point. The blood and serious trauma only arrives with a second, presumably even more assaultive invasion. But it's portrayed unclearly, so I'm confused as to what actually happened.
Not at all suggesting one same-sex rape was more OK than another. Just a little puzzled by their staging.
