I found this quote, but I don't understand it well ...
Those man, what you mean with "not realizing had actually ejaculated", is that they said that they pulled out on time but they actually didn't, like, their intention was to pull out like a "nano-second" before they cum but they fail and a shot actually was inside?Bear in mind that during the Baby Boom in the United States -- a period in history when we had more births than any other -- that withdrawal was the most common method of birth control people were using. Of course, many of those pregnancies may well have been due to men who said they pulled out on time not realizing they had actually ejaculated, and we have no way of knowing what the real deal was.
Or you mean another thing?
