I cannot really endorse this suggestion

I have come across a few websites and blogs that suggest having a shoes-off rule for the reason that when a girl is visiting it will be a prelude to her taking other pieces of clothing off.

As a Christian who believes in reserving sex for marriage I cannot endorse such a suggestion or link to sites that make it. However, if you do adopt this seduction trick, you will find that it does help to keep your home clean. And I cannot object at all to making female visitors more comfortable, whatever your reason for inviting them!
