So Bev isn't as open minded (otherwise known as desperate) as all the people posting in the "who would you do" threads in TNZ who claim they would do anybody. She's just super het but here's the thing.. we know that Janeway would turn her. Because Janeway turns everybody.
We already know that she would do anyone, because y'know... "Riker".
By Season Seven she did it with a dead guy.
(Hey, my Mom has been screwing a dead guy for years. I call him Dad.)
