I didn't say body type though; preference is far more generalized like age or gender. I'm sorry I didn't write that more clearly---I typed out a lot more than what I posted before deleting and posting a very small portion. I also don't disagree with you that power/domination are huge motivating factors for a lot of sexual offenders, but you can't exclude the population of offenders who truly believe what they're doing is natural/acceptable.
Speaking as a victim, one of my offenders fell into that category. What I think is vital for all parents to understand what grooming is and what that process looks like because for most, sexual predators aren't reactionary individuals; they will wait and build the relationship up so that by the time they strike, that child isn't going to be talking. So many walk around with the, "It's never going to be my child..." "Won't happen to us..." air that they're shell shocked when they find out it had happened to them and the very red flags they rolled their eyes over prior, were all there in the making.
Like you, I don't practice the same severity some take anti-touching rules but I do think there is a line between being realistic and being too cavalier. I think your post came off as the latter though I'm not sure that is your intention.
As someone who's experienced the very real consequences of these types of acts, I'm often torn between being too lax with my daughters or too harsh with them. At our last competition of the season, my CP asked our owner/coach if she could take a picture with them and the owner scooped her up and held her between them for a picture. As an outsider, I'm sure that would alarm a lot of people or make them uncomfortable, but I don't have a problem with it. Much in the same way that I don't have a problem with the hugs that my girl's received in preschool, Kindergarten and 1st grade---maybe it's location or age (I don't remember ever hugging a teacher after elementary school) but they don't bother me yet. One day my stance will likely change, but ensuring safe guards are in place for your safety shouldn't be out of the realm of things to consider. At our original gym, our owner hired in an ex-all star, 21 year old guy and he was not even allowed to be on the coaching staff of the senior team because he was too close to their age.
