Originally seductive this utter dreamboat, Adonis! (4)

I believe the answer is:

stud

'adonis' is the definition.
(both can mean an attractive man)

'originally seductive this utter dreamboat' is the wordplay.
'originally' suggests taking the first letters.
The first letters of 'seductive this utter dreamboat' is 'STUD'.

(Other definitions for stud that I've seen before include "Male horse kept for breeding" , "Place of breeding" , "Boss; item of jewellery" , "kind of farm" , "Small jewellery item" .)

I've seen this clue in The Telegraph.
