Something here combines with the stuff about infantilisation caused by us being born earlier and earlier to let our fat brains get out without slaying our mothers at birth, but resulting in our never emotionally maturing 'fully'. That leads to love-making, for example, having its quality of fingers and thumbs baby exploration rather than mallard rape (if we're lucky). But baby love is at odds with strong sexual desire. Whereas, maybe, fantasy play is more in line with the emergence of fetishes and mallard stuff.
