First time for everything

In the 15, almost 16 years that we've been married, Kate and I have never had a couples massage. I have to admit that I am not a fan of someone else being that close to my body anyways, but this should be interesting. Never done it, don't know if I still want it, but I'll try it because Kate set one up for us tonight. I heard there are hot rocks involved, and that they will be placed on different parts of my body for lengths of time. Not so sure about this..
