What about swimsuit editions? 
Even with chicks on the cover, it's still a "muscle mag". Also, I happen to really like the look of fitness-chicks, but to the civilian population (and to 75% of getbiggers) that's the same as being a full-on homo.
Nope, even the "swimsuit edition" comes with a heathy heap of shame. Hell, when you buy the Sports Illustrated Swimsuit edition, the old lady taking your money knows that you are probably not even gonna make it back to your car before you need to crack one off.
