Written by sex educator and body-positivity advocate Ruby Rare, Sex Ed is the practical and fun guide to sex that you've always wanted – but never known how to ask for.

This is the information you should have been taught at school: a no-holds-barred roadmap that covers everything from how the brain is the most important sex organ and how to communicate what you want to yourself and a partner, all the way down to the messy stuff – solo sex, orgasms, touching, kissing, blow jobs, cunnilingus, a**l play, lube, toys, kegels.

After all, sex education shouldn't start and end with putting a condom on a banana.
