The burning question is what size is normal? The answer is that the penis comes in all shapes and sizes and almost all are normal. Research has shown that the average length of the erect male penis is just over five inches (12.8cm), which is probably smaller than you expected.
Irish men are not regarded as being any more or less well endowed as our European neighbours.
Since five inches is the average, that means half of you will have a longer penis than average when erect and half will have a penis that is shorter than average. Now stop fretting and put that measuring tape away!
