You asked what is meant by the term "sexual predator."
The definition of predator is:
1. An organism that lives by preying on other organisms.
2. One that victimizes, plunders, or destroys, especially for one's own gain.
A sexual predator uses sexual activity, exploitation and manipulation as their form of predation.
I was going to use lions hunting wildebeast as an example of predation, but lions don't exploit their prey. They don't continue to torment their victims. Lions prey upon wildebeast to eat and survive. Sexual predators frequently torment their victims, sometimes for many years, and they do NOT need to engage in these activities to sustain life.
Sexual predators engage in their behaviors because they have no regard for anyone other than themselves. Those they abuse are frequently not given any more consideration than any other disposable object.
Some may profess to "love" those they have abused. Personally, I think what they "loved" is the satisfaction of their wants and needs, and they don't give a damn about the person (or people) they abused. If they really did "love" them, they would never have harmed them.
Sexual abuse has nothing to do with love or homosexuality. It is about power. It is about fulfilling one's needs to the exclusion of consideration of anyone else. Most child sexual abusers self identify as having a heterosexual preference, regardless of whether their victims were male or female. It isn't the gender of the victim(s) that attracts them (for the most part) but the person's physical development (or the lack thereof), the access they have to that person and the ease with which they can not only manipulate that person but whether or not they will be able to manipulate them into silence so their sick behaviors can continue, either with that person, or others.

I am glad you are here asking questions. Only by being informed can you help others, including yourself. Some of what you may read may alarm you. Some of it may horrify you. Much of it will tear at your heart. Empathize with us, but do not pity us. We are survivors. We have survived horrific events to which no human should ever be exposed. Rejoice in our strength and in our spirit. We are the Phoenixes that will once again rise above the ashes.
