I just read the website. There are a few things that concern me. They describe it as "alternative", "non-binary",
"...this show is a reimagining of Relationships and Sex Education that is quite different from what we might get at school. It doesn’t give you the facts and stats… It’s about the feelings, it’s about the humanity and it is a theatre show".
"Sexual development and behaviour in children starts from birth."
"We are hoping the show offers an alternative to porn."
"We want to equip young people with a wider critical toolkit which they can then apply to life, including interactions with any kind of porn. So this might include: ethical decision making; sexual consent; equity - the skills to spot gender norms, male gaze, racist tropes, ableism; understanding of safe sex (able to spot non-use of protection), etc."
It also defines being gay as same-gender attracted, not same-sex attracted.
