NETFLIX'S Sex Education has released a seriously crude season two trailer – tackling masturbation, STIs and vaginal bleaching.
The series follows Otis Milburn (Asa Butterfield), a socially awkward high school student who lives with his sex therapist mother, Jean (Gillian Anderson).
In season one Otis and his friend Maeve Wiley (Emma Mackey) set-up a sex clinic at school to capitalise on his intuitive talent for sex advice.
In season two, as a late bloomer Otis must master his newly discovered sexual urges in order to progress with his girlfriend Ola whilst also dealing with his now strained relationship with Maeve.
Meanwhile, Moordale Secondary is in the throes of a chlamydia outbreak, highlighting the need for better sex education at the school and new kids come to town who will challenge the status quo.
The trailer begins with Otis looking mortified when his mother comes on stage in assembly to talk about sex.
Then as the chlamydia outbreak takes hold, one girl pesters Otis with the question: "I've read that I should rub bleach on my vagina, is that true?"
Maeve then makes a bid to return to the school, taking a pile of papers to Head Teacher Mr Groff and saying: "If you let me back in, I won't tell that your school is full of cheats."
A new boy from France arrives and asks out Eric before the two share a kiss.
However, another smooch between the two is interrupted by Adam, who made a shock move on Eric at the end of series one despite bullying him throughout the season.

In another clip from the trailer, Otis and Ola start to get intimate but then they find Jean getting down and dirty with Mr Groff in the living room, his pants around his ankles as he topples over and breaks the coffee table.
Eric then mocks his friend saying: "You finally get a girlfriend and she's basically your sister."
Questions are then raised about the status of Otis and Maeve's relationship, with Jackson telling him: "Maeve broke up with me because she's in love with you."
Otis is then seen getting punched in the face as his classmates watch on, before another scene sees Otis and Maeve walking towards each other in the corridor with a smile.
She tells him: "This is entirely about the money."
As the trailer comes to an end, Otis smiles and replies: "It's good to be back in business."
Sex Education series two premieres on Netflix on Friday, January 17.
