Hedwig and The Angry Inch/Headscratchers

So if Hedwig has no bosom, how did zie pass the physical exam in order to marry that guy? Did zie just pass hirself off as amazingly flat-chested? Also, why didn't zie have breasts anyway? Or did zie just stop taking hormones and has a chest with No Ontological Inertia?
- In one of the songs, Hedwig sings about how her mother made her 'tits of clay'. And, it's not like they would be doing a full cavity search or anything... "Do you, Insert Name Here, look male? Do you, Insert Name Here, look female? Good, you can marry." Any number of real life transgendered individuals are proof enough of that.
  - The thing is, if they weren't doing very nearly a full cavity search, there wouldn't have been any need of the surgery. It's surprisingly easy to hide a standard set of gentleman's vegetables, even to the point of looking convincingly female while naked from certain angles. In the stage version, it's a bit clearer that Luther tricked Hedwig into thinking that the surgery was necessary, even though it wasn't really.
On the subject of the sex change, why the Hell does dilation never come up? Seriously, from Hedwig's account it doesn't even sound like the sex change operation was actually botched, it just sounds like she forgot to dilate. No mention.
- Did Not Do the Research?
- It was a really fast, cheap, and gritty surgery. He didn't know what he was getting into.
