This is asinine. I mean, wat did we learn from this exhibitionis--I mean experiment? Penis size matters for attractiveness. Whether penis size matters for pleasure isn't even tested in this pornogra--I mean experiment, so the headline itself is a bit misleading.
One thing I found interesting was that penis size added to the attractiveness more when the man already had an attractive body (defined as tall and muscular). A man who has a less attractive body, well, his large penis won't help him be attractive to women as much. I think what we can really conclude from this peacock display--I mean experiment, is that body shape matters more than penis size for attractiveness.
