A couple men researched ancient Roman records, and came up with this listing of largest, biggest, and etc. It very entertaining, and your not likely to run across the facts again.
Article contains risque material that some will find offensive and others hilarious.
I never knew the Romans had much of a recording industry. 
One of us! One of us!
To keep the article in perspective, it has only one beatiality mentioned, and it’s now posted. It’s not all debachery, only some. I lists a man over 9 foot tall.
Damn. I think the current record for most number of people banging one vag in a row is up above 300 (I remember at one point it was about 300, with Jasmine St.Claire holding the record, but I’m fairly sure that has been beaten.)
Last I heard it was 500+, so not just beaten, but lapped.
They also mention a lady that was a mime. Mimes are a problem back 2,000 years ago. It’s probably the largest factor in the fall of the Roman Empire.
The miracle of modern personal lubricants.
The ancient Ripley’s Believe It or Not.
(As we told my son, here’s a hint, most of the time, not.)
