Hello doctors, it's a controversial topic, lots of misinformation spread all over the internet so one cannot trust google for the same. Do size/shape (length/girth) of penis really matter in a long term relationship (or marriage)? If yes, then what should be the minimum (or average) size one must have to fulfil his partners wishes & to satisfy his partner on bed? Actually mine is 4.7 inches (from base to tip) & 5.1 inches (from pubic bone to base, after pressing ruler against fat) in length & 3.8 inches in girth (while erect). And after reading too much on google I suppose that mine is small in length as well as in girth is it normal?
