My son has not assaulted anyone that I know of but with his other psychological problems it is a strong possibility, especially with his impulsivity and hypersexuality. Being aware of that has strongly affected my parenting style and skills.
We had one complaint from a neighbor some years ago of “playing doctor” but since both kids were the same age (and quite young) we simply kept the kids apart for a while until the other child was definitely old enough to report accurately if something happened again. I have not heard any other complaints directly so I have to hope nothing has happened.
There is a rumor that he may have been involved with another child, but she is older than he, is the one who taught him certain swear words, and her mother has never contacted me at all. When I attempted to check out the rumor her mother was rude and refused to talk to me. Another neighbor with a son the same age as mine refers to that woman as “That…. witch” so her enmity isn’t strictly directed at me. My daughter also refuses to play with the girl, saying she is mean and a liar.
Just in case, I make sure my son is never alone with my daughter or small children without me or my husband present. He also does not get to spend the night at someone else’s house when there are young children there. The excuse is that he has to take medicine.
In addition, my daughter has a dead bolt on her bedroom door so he will leave her alone when she is sleeping and so he can’t steal her stuff, as he has been known to do. He hasn’t tried anything sexual with her but he does wake her up at times when she needs to sleep.
My son does go to counseling, takes psychoactive medications, and has been in residential treatment. He knows that certain behaviors will lead to a 911 call and possible separation from us.
Although molestation by others is often the cause of a child molesting others, there are other causes. Impulsivity can lead to carrying out such behavior even when the child knows it is wrong. Hypersexuality, a symptom of certain mental illnesses, can also lead to that sort of behavior. Sociopathic tendencies can lead to it as well as can narcissistic traits.
14 year old boys are frequently not in very good control of themselves and so on general principles I wouldn’t leave one alone with a small girl. If one has actually carried out an assault, then the police need to be called and the boy definitely needs counseling, residential treatment, and possibly diagnosis and medication. Depending on the diagnosis he may need to be permanently removed from the home. He certainly needs to be removed for a while.
I have to admit that our house is not a typical one. My son has been known to have psychiatric problems for some time so I have had to develop parenting skills not found in the typical family. I have always encouraged my daughter to be strong and express herself with words. I have always insisted to my son that when a girl says “no” that means “stop right now!” I have always kept a closer eye on the kids than most parents do to forestall any unfortunate events. I know that other parents aren’t as on guard as I am so sometimes a bad situation can seem to occur out of the blue.
In any case, a 14 yo boy is not an adult, and is often not entirely in control of his actions (14 yo boys are still middle schoolers remember). If labeled an unredeemable character at 14 he will very likely live down to expectations for the rest of his life. However, if you can get him treatment, get him to understand why what he did was wrong, and convince him he is still worth loving, he may be able to become a good and conscientious man.
The daughter of course also needs support just as much as her brother, but to reassure her that she did nothing wrong especially if she was indeed innocent of enticement. Most girls would indeed be totally innocent, but bear in mind that a few girls have psychiatric problems as well. I have met a few of them in my experience with residential treatment. Why they themselves behave that way I haven’t known, but I have seen very enticing behavior from some disturbed girls.
In any case, it is our primary job as parents to love our children and to provide them with the best possible upbringing. If this includes hypervigilence and separation from siblings, then so be it.
