vanityobscene asked: I noticed your answer about the sperm in precum and felt the need to use the question box to add to that conversation, for the sake of clarity for us all :). Precum contains, in most cases, no sperm. In the cases sperm were found, the sperm were immobile. This means that precum holds little to no risk of causing pregnancy. I can't share a paper about this topic, but I've posted it as a link on my tumblr if you're interested in reading it. I enjoy your blog! Keep up the good work! :)
