Establishing a position, confess about sex appeal (6)

Ross

I believe the answer is:

siting

I'm a little stuck... Click here to teach me more about this clue!

'establishing a position' is the definition.
I can't judge whether this defines the answer.

'confess about sex appeal' is the wordplay.
'confess' becomes 'sing' (I've seen this before).
'about' indicates putting letters inside.
'sex appeal' becomes 'it'.
'sing' going around 'it' is 'SITING'.

Can you help me to learn more?

(Other definitions for siting that I've seen before include "Locating, positioning" , "Placing in a specific location" , "Installing" .)
