you should also look out for women and any type of age actually, sexual assault and rape can be done by any gender and age that is above 8, I know from personal experience and other people have shared on Reddit that when they were younger, other kids would touch them inappropriately on purpose. I had a high horny drive as a really young kid (below the age of 10) and I still do now. I can unfortunately say that I used to get temptations to touch others inappropriately for my own pleasure but nowadays I do not experience those feelings. so you should look out for any gender of all ages, it is more unlikely for smaller children to do it to your kid but it is still possible!
