Honourably turned on by embracing ladies primarily (5)
I believe the answer is:
nobly
'honourably' is the definition.
'turned on by embracing ladies primarily' is the wordplay.
'turned' says the letters should be written in reverse.
'embracing' indicates putting letters inside.
'primarily' indicates taking the first letters.
The first letter of 'ladies' is 'l'.
'on' back-to-front is 'no'.
'by' going around 'l' is 'bly'.
'no'+'bly'='NOBLY'
(Other definitions for nobly that I've seen before include "With great dignity" , "Worthily" , "In an aristocratic manner" .)
