Washington, September 16 : Daniel Radcliffe has revealed that stage fright makes his genitals 'shrink'.
Going by his revelation, it seems that 'things' all going to be difficult for the boy wizard when he strips on Broadway for the play 'Equus'.
The 'Harry Potter' star played the troubled horse-obsessed Alan Strang in Peter Shaffer's psychological drama in the London West End Theatre production last year.
He realized he suffered from a phenomenon he calls Michaelangelo's David Effect - named after the biblical battle between David and Goliath.
"He (David) wasn't very well endowed, because he was fighting Goliath. There was very much that effect. You tighten up like a hamster," Contactmusic quoted Radcliffe as saying.
But the 19-year-old actor has dealt with the situations quite comfortably.
"The first time it happened, I turned around and went, 'You know there's a thousand people here, and I don't think even one of them would expect you to look you best in this situation,'" he added.
