CollegeHumor’s X-Men Guide To Puberty By Caldwell Tanner [Webcomic]
Following up on his exploration of superhero sex positions, CollegeHumor cartoonist Caldwell Tanner is back with another intimate series based on the personal lives of some of our favorite comic book characters. In the "What's Happening To My Body?" Book For Mutants, Tanner casts Professor X as a sex education teacher giving his mutant students some crucial understanding of their variously horrible bodily functions.
