Ten times? I know you are just tossing out a number because that one doesn’t sound like it was based on any actual statistics. I don’t think fathers are even one tenth as likely as mothers’ boyfriends to sexually abuse their children. I think that it is much more rare than that.
Yes, tossing. But the statistics are as you state. It’s almost de facto abuse to introduce a strange man into the life of your female children. Assume he will abuse simply because it’s so statistically likely to happen.
