Boudoir photography is a photographic style featuring intimate, romantic, and sometimes erotic images of its subjects, primarily intended for the private enjoyment of the subject and their romantic partners.
It is distinct from glamour and art nude photography in that it is usually more suggestive rather than explicit in its approach to nudity and sexuality, features subjects who do not regularly model, and produces images which are not intended to be seen by a wide audience, but rather to remain under the control of the subject.
It is common for women to have boudoir photographs of themselves made as a gift to a partner, conventionally on the occasion of their engagement, marriage, or before an enforced separation such as a military deployment. Boudoir photography is also sometimes given as a gift with the intention of re-affirming and encouraging the romance and sensuality between partners in a long-term relationship.
Increasingly, boudoir photography is seen as something that a person might do purely for their own enjoyment, for the pleasure and affirmation of seeing themselves as attractive, daring, sensual, and sexually-desirable.
This is what Wikipedia say about Boudoir photography.
What I say is that every woman deserves a boudoir photography session, not only as a gift to her partner but as a gift to herself too...
