To Eric, possibly titillating (6)
I believe the answer is:
erotic
'titillating' is the definition.
(synonyms)
'to eric possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'to'+'eric'='toeric'
'toeric' anagrammed gives 'EROTIC'.
(Other definitions for erotic that I've seen before include "Sexy" , "Conducive to arousing sexual desire" , "Titillating" , "Tending to arouse" , "Sensual" .)
