Ah, science. Answering all of the important questions... and confirming for once and for all what size of an appendage is most appealing.  Researchers from the University of California and the University of New Mexico attempted to answer the ultimate cock conundrum recently by creating 33 variations of penises (in 3D model form) and asking 75 females to pick the size they prefer for a long-term partner and for a one night stand. The choices were 3D printed in blue plastic "to minimise racial skin-color cues". The results would suggest that women like them big, but not too big. The majority of women surveyed chose a penis model that was "slightly above average". Said average was based on previous studies which put the average American erect penis length at six inches. Of the phallic shapes, most women opted for a 6.3 appendage for a long-term partner. When asked to consider a one-night stand, the size was slightly bigger at 6.4 inches. Speaking to The Daily Beast, Dr. Nicole Prause, who led the study, said: "Since context matters, men should be thinking ‘fit’ rather than ‘fat’ with respect to their penis size. In other words, women may prefer different sizes for different reasons at different times, so chances are very good any guy is someone's ideal for the relationship type they are seeking."
