It's exciting, kinky Latin smut (9)
I believe the answer is:
stimulant
'it's exciting' is the definition.
(thesaurus)
'kinky latin smut' is the wordplay.
'kinky' indicates anagramming the letters.
'latin'+'smut'='latinsmut'
'latinsmut' with letters rearranged gives 'STIMULANT'.
(Other definitions for stimulant that I've seen before include "Booster" , "Tonic, pick-me-up" , "Increasing vital action" , "Means of prompting action" , "Drug to make one more vigorous and active" .)
