Lascivious stare led reader without fear inside (4)
I believe the answer is:
leer
'lascivious stare' is the definition.
The definition and answer can be both to do with perception as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for leer that I've seen before include "Look lasciviously at" , "Gaze lasciviously at" , "Look lecherously" , "Suggestive or sneering grin" , "Give lascivious look" .)
