Nick Youngquest Touches Himself...

And he wants you to do the same.

The Australian rugby hunk has posed in the buff for a series of head-turning ads aimed at raising testicular cancer awareness, and catching the disease early through self-examination. The UK campaign, by MacMillan Cancer Support, urges men to "Checkum," and immediately see a doctor if anything suspicious is discovered. (Click here for MacMillan's self-examination instructions).

Other celebrities who bared all for the campaign include; Dale Howard (Big Brother), Marcus Patrick (Hollyoaks), Matt Evers (Dancing On Ice), and Alexander Campbell of the Birmingham Ballet.
