Sasha Zlatanovic Posted about 2 years ago Al Vernacchio: Sex needs a new metaphor. Here's one ... I agree with you and I posted similarly but it seems I was wrong to the extent that the pizza metaphor seems to be a joke I didn't get. The speaker has said in his posts that pizza was used only to contrast baseball and to quote him "I don't want people to talk about sex like pizza. I want them to talk about their desires, needs, and wants openly with their partners and not need coded language to do it." The fact that this metaphor is only found in the US while the corresponding mentality exists everywhere still leads me to think the metaphor is as you said only a reflection of a pre-existing "problem".
