There is certainly no dearth of hunky athletic calendars, and today we add another to our growing list of sportsmen willing to get naked for charity: This time, Panteres Grogues, a Barcelona-based gay sports league, is offering up their nubile bodies to raise money for the BCN Checkpoint Center, an HIV testing organization. The center is the first of its kind in Spain, and is managed by Projecte dels NOMS-Hispanosida association.

According to the Huffington Post, the Panteres Grogues is a recreational athletic organization for queers looking for a safe place to get their sport on. “Our first calendar sold very well and helped the financial situation of the club," explained Mano Ventura, the group’s coordinator, "This year with our financial situation much better we wanted to do it again to have some fun and publicize the club but this time also to collaborate with an organization who does an excellent and worthwhile job.”

If you want to brave the uncharitable exchange rate and support this HIV/AIDS charity, you can purchase the calendar over here, and below we've collected some of our favorite photos by JP Santamaria from the series:
