It has happened to us, while traveling, to end up with a hotel room with mirrors on the ceiling. We found the experience both amusing and exciting: when having sex man on top of woman or woman on top of man, the bottom partner has an excellent view.
We are however unsure whether we would like that every day, and besides it could be embarrassing if somebody came to visit our bedroom (we probably seem very vanilla to family and friends) so we do not have any at home.
Any thoughts or experience about that?
