K-Y Jelly Complementarianism

In a strange way, I'm thankful for the recent K-Y Brand lubricant advertising in my local paper, The San Francisco Chronicle. Why? K-Y's new product, yours+mine, assumes that men and women are different and that sex is an activity for one man and one woman to engage in--assumptions quite contrary to the gender and sex values normally promoted in my local paper.Perhaps K-Y is an ally in expounding a complementarian understanding of the sexes.
