Meet the "hormone monsters."

They are the hairy, scary beasts of the Netflix animated series "Big Mouth" who torment the minds and bodies of middle-schoolers in the throes of puberty.

Everything is monstrously confusing, a little out of control and a very big deal. "Big Mouth" is funny and raunchy, and one of several streaming shows being praised for their bold and compassionate portrayals of teenage sexuality.

"We all found that time of life to be this potent time when you're trying to figure things out," says Jennifer Flackett, co-creator and executive producer of "Big Mouth," about the show's conception. "And we, at the time, had a 13-year-old son. We were just watching him kind of go through the throes of puberty. We were sort of thinking, 'Is there a way' — because we knew the show was going to be animated — 'to talk about that?' ... We wanted to kind of give a voice to that voice inside of you."

What does that voice inside of you look like? The "Hormone Monstress" Connie yelling at the character Jessi to "scream at her mother than laugh at her tears." And the "Shame Wizard" accusing the character Andrew of being a "loathsome little pervert." These are the kinds of chaotic internal monologues, indictments and worries we face in puberty.

"Sex Education," another Netflix hit, and Hulu’s "Pen15," are also changing the way teenage sexuality is shown on the small screen. Right now, only 24 states mandate sex education in schools, and 13 of them require the instruction be medically accurate. So teens go where teens go for comfort and camaraderie: to the culture.

And that culture is online. In Flackett's eyes, a show like "Big Mouth" would not be possible without the freedom streaming services provide.

"I think the show became what it is because we were on Netflix and because of the freedom that we had there," she told On Point. "Because there's no content restrictions and because they have just been the most incredible partners of letting us figure out what the show is and celebrating that."
