Okay, maybe not (10)^100th time, but quite a few times, this question has been asked. Allow me to make a few points. 1. This question is subjective. It is not like asking what the average penis size is. That of course is an objective answer. There is only one average size. However, the question, "what do you 'consider' big" has different answers based on the individual. 2. The female (or male for that matter) perception may be off. I suspect this happens nearly 100 % of the time. The person making measurement (N) will almost always not be able to visually understand what "X" inches looks like. This means that we are really trying to ask the question, "if the person did have a visual understanding of size, what would they consider big". 3. In relation to (2), do we really understand what we mean by size. We determine "size" by making a physical measurement. But how is this to be carried out? Is it to be bone pressed. The answer to this is simple, what one would want to do, is perform measurements in the same manner as the study they are comparing themselves to did. Thoughts?
Don't know where you're going especially, but my answer is anything over 8 inches in length is big and anything over six in girth. Of course 8"x6" is well over average, but there's enough guys on here at around that size to make it seem not really rare. Also, it's fairly average porn star inches.
Size, like beauty, is pretty relative.There are many factors to consider. A woman who has experienced a genuine 9 incher or bigger, will have a totally different perception on size than a woman who has experienced 6-7 as her biggest. What is known, is that the average size is about 5 1/2 statistically. So going by that, once you get into being an inch or more larger, you're going from average to above average to big to huge and so on, the further along the scale you go. Me personally, if you're sufficiently above average, that could reasonably be considered big.
