Puts on parties for men full of energy (6)

I believe the answer is:

stages

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

'puts on' is the definition.
(I've seen this in another clue)

'parties for men full of energy' is the wordplay.
I cannot really understand how this works, but
'men' could be 'stag' (I've seen this before) and 'stag' is found in the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is located in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for stages that I've seen before include "Platforms for performances" , "Positions or points in a process" , "legs" , "Shows" , "Engineers" .)
