Too effusive about stripped off male partner (3,4)
I believe the answer is:
all over
'too effusive about' is the definition.
(as in being all over a person)
'stripped off male partner' is the wordplay.
'stripped off' means to look at the middle letters (the outer letters are stripped off).
'partner' becomes 'lover' (romantic partner).
The central letters of 'male' are 'al'.
'al'+'lover'='ALL-OVER'
(Other definitions for all over that I've seen before include "covering everything" , "very characteristically" , "Obsessed with" , "Everywhere (bar the shouting?)" , "typically" .)
