Well, unless you've had considerable training in telepathy, it's unlikely you have any real idea why he's gone all shy on the subject.
For example, would it come as a suprise to you that many men are completely weirded out about the idea of having sex that close to a baby?
He may be concerned that he could hurt you or the baby.
He may have no idea what is and is not okay to do when there's a baby in there.
In fact, he may have a lot of unanswered questions about your body and the baby that are all deep, dark mysteries to him, to the point where he can't even really think of how to phrase the questions. Most medical professionals know a lot and have no idea how little the average guy knows about human fertility, or how sex works during all these changes, so they often don't think of answering unasked questions, they assume people know about as much as they do.
Try talking to him instead of guessing.
