The Red Hot boys are back and they are leaving nothing to the imagination.

Over five years, four calendars, an art exhibit, and two coffee table books, Red Hot photographer Thomas Knights has given us some of the most stunning carrot-tops in nature.

In addition to working on a new 2018 calendar, Knights and Red Hots art director Elliott James Frieze are back to bring awareness to Testicular Cancer with a an additional 2018 calendar called Red Hot C*cks.

Yup, the subjects are stripping down completely naked.

According to the project's Kickstarter page, the calendar will raise money for the Movember Foundation's Testicular Cancer Awareness. The idea was thought up by Knight's friend, artist Andrew Salgado, during a Red Hot photo exhibition.

“Sadly, there is still a lot of hate and bullying surrounding red hair, and this calendar will help show just how sensual ginger pubes can be,” the Red Hot team told the Independent. “With 47 per cent of British men diagnosed with testicular cancer being younger than 35 years old, this is an urgent cause."

You also have the chance to be one of the guys to strip down for the calendar. Knights is looking for more boys to fill the months of the year and if you "have a great body and an amazing fire crotch" then you can reach out to the guys behind Red Hot directly on their Facebook page.

Red Hot is hoping to raise £6,500 for the Movember Foundation's Testicular Cancer Awareness, so head on over to the project's Kickstarter to learn more about how you can help make this calendar a reality.

"12 guys. 12 copper knobs. Because ginger pubes are awesome and your life needs more color."

You can say that again.
