I raced about with half-cut cads to see stimulating art (7)

I believe the answer is:

erotica

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for erotica that I've seen before include "writings about sex" , "Sexual literature, art etc" , "Blue stuff" , "works to stimulate passion?" , "Porn" .)

I've seen this clue in The Independent.
