Even Solomon (1979)

Stephen (Paul Henley) works in a bank. A virgin, he shows no interest in sex, and is cruelly scorned by an aggressive female neighbour when he rebuffs her advances. He lives with his mother, an overbearing woman who mocks him for being wet. But Stephen has a secret – he likes to wear women’s clothing. When his horrified mother finds out, she takes him to meet a fellow cross-dresser to ‘solve’ the problem. But the meeting ends unexpectedly, when the other man realises that Stephen is not transvestite, but transsexual.
