Conceived and designed the experiments: NP GM. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference. These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average.
Out of the women who often experienced vaginal-only orgasms and had enough partners to compare sizes, one third said they preferred longer-than-average penises. What exactly does "average" count for these days? Science reveals the average penis size.
The average girth is 3. Girth is the circumference of the penis at its widest section. The BJUI research used data from 17 studies, and the study participants totaled more than 15, men.
In order to measure this we first have to make some assumptions about the average penis size, the average duration and the average speed. So let's start the calculation. Medical studies have shown that the average penis size is 13cm we assume a penetration depth of 11cm. As the average duration we'll take the average time from entering the vagina - or wherever it enters ; - to ejaculation - no foreplay.

Each year our obsession with penis sizes seems to keep growing, with the subject even making its way into the US presidential elections last year! For the most part however, it seems like it's only men who are fixated with phallic size, with any insinuation of a man having a small penis being a direct affront to his honor or 'manhood'. But what is it that women think and does penis size really matter in bed?
According to an online survey of 25, participants, almost half of all men wish their penises were larger. Concerns surrounding penis size have become so pervasive that some psychologists have come up with a very obvious name for it: small penis syndrome. In fact, the average erection measures 5. And it gets the job done.
A recent study published in the British Journal of Urology claims to have finally laid the kibosh on the considerable debate surrounding the average size of the penis. While there have been previous attempts to quantify average penis size, these studies varied considerably in measurement of flaccid and erect state, racial groups, age and whether measurements were conducted by a professional or by the participants themselves who may have felt inclined to fudge the numbers somewhat. This most recent study from the UK conducted a systematic review of twenty previous studies of penis size which included over 15, men from a diverse range of ages and ethnic groups.
