I believe that every guy tests himself at least once to see how many times he can "do it" in a night. If he has the opportunity. But it is always with a wife or girlfriend. A man who is a rock star, or a movie star, or a basketball star, could find several women willing to try it at one time. Or in the making of a porn movie. But for an ordinary guy, like me, usually it is with one woman.
I remember an exception to that statement. Back in the 1970's there were "Key Parties". Friends would get together at the host's house and drink, and everyone put their car keys in a large bowl. When it was time for everyone to go home, the woman would pull out somebody's car key, and go home with whoever owned that car. It was simple wife swapping for the night. There is an excellent movie about it, titled "The Ice Storm".
Also in the 70's some people went one step further. They were "Swingers". A friend of a friend of mine was a real estate developer in Florida. He belonged to a swinger's club. They would meet at the host's mansion. He had the nickname "The King". A heavy set man and a multi-millionaire. He gave his guests plenty of food, drinks and drugs.
There was a mattress in the middle of a huge living room. A man or woman would chose anyone there and have sex in front of everyone. But each person had to have a strong libido to stay in the club. A man had to have at least 3 orgasms that evening, or else he would not be allowed back. Cumming 3 times in 3 hours is not hard if you are 16, but try it when you are 35 or 40. There was no Viagra back then.
(I won't say how many times I personally got it up on one sleepless night, but Pierre beat my record.)
