Sex Education: parents' guide

Mostly bullying, shoves, slaps and a homophobic attack on a gay teen. Sexual violence: a man on a bus masturbates on a girl, and her trauma plays out over later seasons. A boyfriend assaults his girlfriend, and a flashback shows a girl abused at 12.

Heavy profanity: one count of the first episode found about a dozen each of f-words and s-words, plus "piss," crude anatomical terms, the insult "slag" and an anti-gay slur.

Very explicit: teens and adults have graphic sex with movement and noise, and men and women are shown fully nude, including genitals. Masturbation, pornography, sex toys and blunt sexual talk run through nearly every episode.

Underage drinking and smoking are casual and frequent, and teens smoke marijuana, once with a friend's mother. A teen takes Viagra. A main character's mother struggles with drug addiction, relapses and dies of an overdose in the final season.

Not scary, but heavy at times: panic attacks, the lasting trauma of the bus assault, a teen reporting her own mother to social services, and a parent's overdose and funeral.
