What is the difference of these two words and how are they applied? Which is for inanimate things, and which applies to humans?

I saw the movie Animal House, wherein the college dean's seductive wife corrects the flirtatious fraternity boy's word choice when they met in the produce section of the grocery store. I wish to know if a distinction remains between the two words, or does it even matter these days?

Here's a cool tip for looking up words. Google this:

define: Sensuous

and then

define: Sensual

It gives you dictionary definitions without having to go to a website. It's pretty useful.
