Diaphragms

My church recently elected to read The Purpose Driven Life as a body and thus the congregation has been divvied into small groups, one of which KS and I agreed to host. The small groups meet once/week and are intended to spark soul-searching conversation among the members. The members of our small group, unfortunately, were all raised in Christian homes, thus we "know it all" and hence become distracted far too easily. Last week, for example, we couldn't stay away from the topic of sex. I swear we will all burn in hell for the sexual innuendo and snickering- during-prayer that took place last week!
This week proved better, but only slightly. Somehow, and I am quite sure this was my fault, the topic of female condoms was broached. During the course of this holy conversation KS, apparently unfamiliar with the land of diaphragms, asked "so how exactly does it work? I mean, how do they keep it from moving due to blunt force trauma?"
And that folks is the first, and I am sure the last time, I will ever here the phrase "blunt force trauma" used in a good way!
