Testino on Testicles

In my dissertation I'm writing about Mario Testino and his perception of male fashion photography (or something to that extent). Testino says that although he loves to photograph men the depth of their vanity is limited. I find this arguable but his work speaks for itself. The images he has captured of men are fantastic, but I wonder whether he believes that to be the full extent of the man's place in fashion. It's taking us a long time to come to terms with the fact that yes, men moisturise, but I think the 'depth' of men's fashionabilty is growing.
