Individual needing to make contact but also putting up boundaries (6)
I believe the answer is:
fencer
'individual' is the definition.
(fencer is a kind of individual)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for fencer that I've seen before include "Maker of barriers; user of foil" , "He sports with swords" , "One encloses" , "One with flashing blade" , "armed fighter" .)
