Not sure about the bad image.
If a guy has multiple sex partners, he becomes a stud (as a complement) , but we think if a girl does the same thing, it is a bad image.
I think Sara is a very strong girl. She is totally in charge of the men she gets close to them. As soft as she is with them, she never let them do things she doesn't want.
I really like Sara character. She is so strong and social.
