Abusers can be homosexual or heterosexual. Children almost never invent stories of sexual abuse. Children don't play games with something as serious as this nor do they have the knowledge to invent details of this type of assault. It could be a professional or a homeless person. There is no typical socio-economic or intelligence profile for a paedophile.
Most child abuse occurs in either the victim or the offender's home.
It typically starts with touching and may evolve to intercourse. In many cases, the abuse grows over a period of time as the offender exercises greater control over the victim. Equip The Child Without spooking them to nightmares, children have to know about the dangers of sexual abuse. This will not only give them knowledge to protect themselves but it will also make them more open to divulge abuse should it occur. An ounce of prevention is worth a pound of cure.
