An extreme fascination or sexual fantasy about giants.
There is a divide, SM and Mega within this paraphilia.
SM refers to where a person becomes shrunk in size, and is then placed at the mercy of a normal sized person.
Mega refers to where the attraction is to someone exceedingly larger than they are, as told in fairy tales, where again they are at the sole mercy of the now larger than normal, person.
Sexual fantasy includes being eaten, being sexually used and abused, sexual gratification of the Giant being, humiliation, gentleness, and more.
This can include one having an evil persona, be about a rampage, toilet scenes, spitting, and so on.
Most who are Macrophiliacs, are shy and reserved, often not revealing their fetish, due to fear of ridicule.
