The other day I wrote about the surprising efficacy of withdrawal as a method of pregnancy prevention. Several commenters wrote in, saying, “But… precum!”
This is an interesting example of the phenomenon I wrote at greater length about a year or so when I was writing about safer sex. People disregard science in favor of their emotions when it comes to evaluating the risks associated with sex, and their emotions are informed by all sorts of fears and shame, puritanical and otherwise.
The study to which I linked includes the risk presented by precum. Period. So saying, “BUT PRECUM HAS SEMEN!” is a non-sequitur. Yes, precum has semen in it.
And the study assessed the risk of pregnancy from sex in which the method of pregnancy prevention used was withdrawal.
