I have been talking about non-sex sexuality issues way too much lately. (Academia made me do it.) Check out this awesome infographic from the KoldCast TV blog. A little heteronormative but edutaining nonetheless.
Edited to add: Scarleteen pointed out the sex myth reinforced in this infographic: clitoral vs. vaginal orgasms. An orgasm is an orgasm is an orgasm, which is controlled by the brain.
