When I interviewed Cynthia Fine, Community Health Educator at Planned Parenthood of Greater Washington and North Idaho, a few months ago about painful sex, we had a great, in-depth conversation about not only pain during intercourse, but sexually transmitted infections; the importance of creating a positive, supportive atmosphere if you're having sex; good communication; and a whole raft of other topics. I had a lot to say and only a little bit of space to say it in, and inevitably, I left something important out. I want to fix that by saying a few words about choosing a good lubricant.
