What normal adult human male that is not homosexual can honestly say that he is NOT sexually aroused (even a little bit) by a pretty little girl demonstrating that She is willing to participate in a sexual encounter. True, She may not understand what She is doing, but a normal adult human male that is not homosexual will be affected.

So, your premise cannot be science fiction but, rather, science.

I am Sooooooo affected by Them, though.
