Daniel Radcliffe doesn't get wood when he strips down and kisses co-star Joanna Christie on-stage in Equus. Said Radcliffe:
It's the least arousing process. ... Jo's beautiful, but after you've gone through it a hundred times with an audience there ... to be honest, when you get naked in front of 900 people, quite the opposite happens.
Right Daniel - it's all the people there. Has nothing to do with the fact that girls just don't arouse you in general. It's okay - it happens. It's called gayness and it's a wonderful thing. If you need help dealing with it, just look up the Crabster - he'll take you on the tour. For free.
