In some romance novels, you may come across terms like 'the core' or 'the center'. These are used to describe the vagina in a more veiled way, as romance novels usually aim for a certain level of propriety while still being sensuous. They might also use 'the womanly part' which is a rather general but still a way to refer to it without being overly explicit.
One more name that might show up is 'the temple of love'. This term was used to give a sense of sacredness to the female body part. It was often used in a more flowery and elaborate writing style typical of classic romance novels, making the description more of an artful and romanticized concept rather than a blunt anatomical reference.
Once, a friend was doing a theater play where she had to pretend to be a clumsy waitress. As she rushed across the stage, she tripped and her skirt flew up, and she humorously said 'Well, at least my vagina didn't make an unexpected cameo!'. It was so unexpected that the whole audience burst into laughter.
In some cases, it could be misconstrued as a'myth' due to lack of awareness. But in the medical field, these are real situations that are studied and understood. Specialists in endocrinology and genetics often deal with such complex cases to provide appropriate medical care and support.
I think you should approach it with sensitivity and respect. Avoid being vulgar or objectifying. Focus on the context and the character's emotions related to it.
No. It is not a common type of fanfiction at all. Fanfiction typically centers around established characters, relationships, and storylines from a particular source material, and this description doesn't conform to normal fanfiction themes.
Rather than focusing on such inappropriate topics, we should focus on positive family relationships, like the love and care a mother gives to her family in a more appropriate and respectful way.
