Ok massage experts...help settle a debate [View all]

So tonight was registration for our son's elementary school. My wife, the most amazing PTO mom, was working registration and helping parents through the process, so the actual registration process fell to dad. After registration, my son and my teenage daughter went to my mom's for the night and my wife and I treated ourselves to a couples massage. Enter the conundrum and hopefully you fine folks can provide some insight.

When one is partaking in a massage, do you remove your undies? My wife says "Take off the bra but leave the undies", but I've always been more on the commando side. So, who's right here? Is there even a right or wrong?? FYI, we both agreed that late evening cocktails after a great massage are a must!!
