Leticia Martín-Fuertes Posted almost 2 years ago Al Vernacchio: Sex needs a new metaphor. Here's one ... Brilliant. Maybe this guy took the idea from the famous meme "Sex is like pizza. When it's good, it's good. But when it's bad, it's still good". Seriously now, of course pizza is a way better metaphor to talk about sex, nobody can't agree with that. But aren't we too grown-ups to keep needing metaphors? I mean, can't we talk about anything with their appropriate names? I'm in my twenties and I have girlfriends my age who keep lowering their voice every time they say "vagina", "masturbate", "erection"... Shouldn't we have gotten over all that "shame"?
