I can thoroughly recommend Joe Orton and its interesting to have Kenny Williams's diaries alongside as you read it, to see how two different people describe the same day and same incidents. But I wouldn't leave it around if you kids in the house....Orton writes extremely vividly about his sex life, with copious detail.
In one bit, he meets Kenny in a park somewhere and he tells him to "have fun with his genitals now, otherwise he would regret it when he is older " !
