A sub-trope of What Is This Thing You Call Love?, this refers to the examples where the character is completely deprived of any hang-ups and inhibitions humans usually feel in connection with sex. This might be because they are aliens, or have No Social Skills due to an offbeat background, or live in some sort of utopian/dystopian universe. For this reason, they have no qualms about taking their clothes off in the presence of other people, and may pose a question along the lines of the trope title to anyone who they suspect of being attracted to them.
