Ogle sexy men regularly seen out of bed (3,2)
I believe the answer is:
eye up
'ogle' is the definition.
(to eye someone up is to ogle them)
'sexy men regularly seen out of bed' is the wordplay.
'regularly seen' means one should take alternating letters.
'out of bed' becomes 'up' (synonyms).
'sexy'+'men'='sexymen'
The alternating letters of 'sexymen' are 'eye'.
'eye'+'up'='EYE UP'
(Other definitions for eye up that I've seen before include "Look at (someone) as a potential partner" , "Ogle" , "Eagerly watch" , "Look at (someone) appraisingly" , "Appraise" .)
