I just want to thank Amand Ridley for all her help on this manuscript, from the ideas to the data protocol and the endless stream of drafts.
On a different note, a very interesting paper was published in PNAS investigating female preference for male penis size:

It is an interesting paper, investigating a selective pressure that has had various levels of support from past studies. It is interesting to think of how this preference is manifest in the modern world.
