Elevated rumours about start of sex or congress? (7)

Ross

I believe the answer is:

session

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

'congress?' is the definition.
(I know that session is a type of congress)

'elevated rumours about start of sex' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is present in the answer.
This explanation may well be incorrect...

'or' acts as a link.

Can you help me to learn more?

(Other definitions for session that I've seen before include "Period devoted to an activity" , "School term" , "Meeting devoted to a particular purpose" , "Parliamentary period" , "Time in legislature" .)

I've seen this clue in The Independent.
