Book excerpt: A muscled guy radiates strength of purpose, assertiveness and - last but not least - lots of sex appeal.

So, after the success of the anthologies Turnon: Tattoos and Turnon: Sports, we decided to continue the series with a bulky new photo compilation - Turnon: Muscles. We collected the best pictures of renowned photographers, who brought the male body as a piece of art into the spotlight.
