Assessing sexual orientation in Britain

From the article regarding David Akinsanya, the BBC correspondent who is pursuing reorientation but also consulted Qazi Rahman, British researcher: “Akinsanya underwent a number of tests (at Rahman’s lab), including measurement of his response to sudden loud noises and assessment of such spatial skills as his ability to rotate cubes conceptually. Both types of tests differentiate strongly between heterosexual and homosexual subjects. Akinsanya says he came out as “gay, gay, gay!” in every test.”

Now I wonder if Dr. Rahman also felt the bumps on David’s head?
