No, that's what the word boundary operator does: \b requires the match
to be at a "boundary" where a "non-word" character (or beginning/end
of string etc) meets a "word" character. See the perlre manual page
for details.
Or just try it yourself:
$ perl -ne 'print if m/\b[Ss]\W{0,3}[Ee]\W{0,3}[Xx]\b/' <<HERE
> sex
> s::e::x
> essex
> sussex
> asterix
> disannex
> vasoreflex
> HERE
sex
s::e::x
I.e. only the two "sex" and "s::e::x" matched and were printed.
