Story of ignorance very common in small isolated barrios in the Philippines. The movie however exaggerated the sexual orientation of the people.
This movie was produced during the era of the Experimental Cinema of the Philippine when some starlets in local show business were exploited to create sex-oriented movies. Marcos was still in power, and maybe this passed his approval to divert Filipinos from the worsening political and economic problems. Most of these experimental cinema allowed "pene" so don't be surprised if the there were actual "penetration" in this movie.
