The outlines of this idea are still vague.
Basically this would be the story of a young woman who has a preference for older, sexually dominant men.
The story would cover her time with three such men.
The present would be with one of those men.
But we would also feature flashback scenes to two previous relationships.
Basically these would be the rough outlines of those men.Guy 1
Her boyfriend in the present time
In his late 30s
Plain clothes cop
Sexually dominant but his tastes are not too extremeGuy 2
This would be the guy she was with prior to Guy 1
In his mid 40s
I see him as a self-employed man with a small but successful business
He would be into rough sex, public places and group sex
The relationship would have ended because his tastes turned too extreme for her
He would also have been into sharing her with other menGuy 3
The guy she was with prior to Guy 2
In his late 50s
This would be the man who introduced her to a different sort of sex
He would have been sexually demanding, but not as extreme as Guy 2
He would have ended the relationship upon moving to the other side of the country
The idea is to start the story with her current boyfriend but then intersperse the tale with flashbacks to Guy 2 and Guy 3
