A gentleman might think of not only his own hygiene in general, but of those items intended to make any post-whatever romance statistically of less consequence for those involved. It is rumored that weddings are one of those events which stir female passions and make them suppress briefly their better judgment about such things as the somewhat more cavalier attitude of the opposite sex toward, well, sex.

It might not hurt to contemplate such things for your EDC, if they are not already included in your "be prepared" kit.
