Do aliens have towels? (Details)

Obviously a hypothetical question…

Aliens, as smart as humans, or more.

Do they have stuff to spill?

Does their gravity require different “cleaning” techniques?

So they shower, and therefore require drying?

Would they rather sit in a piece of cloth, than a surface?

Does their planet have appropriate materials to construct a towel?

Do they have obvious sex organs, to cover in modesty, or privacy?
