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?
