These astronauts undergo rigorous medical checks where every inch of their body is checked and double-checked. And they already come from an armed forces background where detailed medical checks are very common and there is zero shame about nudity. I am pretty sure they would not have had qualms about it if it was indeed necessary. Their space suits are already sized to their specific dimensions. Also, why does the sheath size have to be such a public thing?
