Q: I have read about people becoming sick from swallowing too much semen. How much is too much?
Dr. Klein: A very, very small number of people are allergic to semen. Other than that, no one becomes sick from swallowing semen, and so there is no such thing as “too much.” Of course, if someone does not like to swallow semen, the tiniest amount is “too much.” No one should be urged to swallow semen–or even have it in their mouth–if they don’t want it.
