One part of me subconsciously turns on another man (5)
I believe the answer is:
diego
'man' is the definition.
'one part of me subconsciously turns on another' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'of' could be 'o' and 'o' is found within the answer.
The remaining letters 'deg' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for diego that I've seen before include "San --, -- Garcia" , "Spaniard potentially" , "Spanish male forename" , "-- Garcia, Indian Ocean island" , "Maradona, say" .)
