Hates men being confused over sex that is satisfactory (8)
I believe the answer is:
enmities
'hates' is the definition.
(enmity is a kind of hate)
'men being confused over sex that is satisfactory' is the wordplay.
'being confused' indicates anagramming the letters.
'over' says to put letters next to each other (in a down clue, some letters go over others).
'sex' becomes 'it' (a common euphemism).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'satisfactory' becomes 's' (abbreviation in education).
'men' is an anagram of 'enm'.
'enm'+'it'+'ie'+'s'='ENMITIES'
(Other definitions for enmities that I've seen before include "States of deep-seated ill-will" , "Hates" .)
