I did a little googling to learn what really constitues an Irish person before answering your thread. My gosh, what a diversified genetic pool.
The earliest known Hibernian people had their genes added to by the Northern French, the Spanish, the Greeks, the Celts and the Vikings.... this includes genes from all over Europe and the Middle East as well , considering that Turkey and Persia are frequently thought to be the origin of the nomadic Celts. I should guess that there is extreme diversity in cock size as well.... similar to what one finds in a diversified genetic pool such as the U.S. Therefore, I can not contemplate what the typical Irish cock would be like or how large it would be sized!:wink:
