In relation to lovemaking, I’m truly conservative (7)
I believe the answer is:
amatory
'in relation to lovemaking' is the definition.
I can't judge whether this defines the answer.
'i'm truly conservative' is the wordplay.
'i'm' becomes 'am' (I've seen this in other clues).
'truly' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'conservative' becomes 'tory' (informal term for a Conservative Party member).
'am'+'a'+'tory'='AMATORY'
Can you help me to learn more?
(Other definitions for amatory that I've seen before include "Passionate" , "relating to sexual desire?" , "declaration of love" , "Loving" .)
