Sexual abuse is a relative cultural term used to describe sexual relations and behavior between two or more parties which are considered criminally and/or morally offensive. Different types of sexual abuse involve: Non-consensual, forced physical sexual behavior such as rape, incest or sexual assault, or psychological forms of abuse, such as verbal sexual behavior or...
If you are concerned that there may be underlying abuse occurring with this girl then you could keep an eye on it and look for reoccurring patterns in her behaviour/actions and also how the other siblings are responding to her when this happens.
Another indicator is how she responds to males when they come near her....if she shys away or looks distressed.
From what I've read and what the Police have told me a female child who is being abused by a male adult often slightly flinches when the male goes near them. They also tend to be slightly withdrawn, don't engage in group activities as much as other kids and interestingly enough.....the types of art drawings they do and the way they play with their dolls can often indicate a few things too.
My personal opinion on homeschooling is that it doesn't allow the child to socially interact with others of their peer group as well as those who attend a school through the system (be it either public or private schooling).
It's quite possible that they are acting out and mimicking what they have seen in books and movies and possibly other adult interaction they may have seen out in the street/malls etc but if you are truly concerned and you feel that there is something not quite right about it then go with your gut instinct and observe and monitor the situation.
It may turn out to be a harmless phase that they are going through, but then again it may not and you may be right in thinking that there is something untoward going on.
You could always grab some pamphlets on child abuse from the local police station, they usually have pamphlets of some sort, or you can google the web for more info so that you yourself can be more aware of the signs etc.
Either way, go with your gut instinct.
