Trying to use bind variables with a list

Question

I have the following dynamic SQL statement which I'm trying to convert to use pure bind variables. the variable "v_list" is a string that gets filled dynamically with a list of numbers so it can be used in an expression "IN (<expr>)". The number of elements is not constant but DB driven. I cannot simply replace it with a bind variable, I get the "Invalid number" error.
I read up on using collection/varrays but they seem to be build for other purposes. any ideas?
BTW this query catcehs the NO_DATA and TOO_MANY exception. basically we are interested in either found at least one record, or not.
DECLARE
     v_list     VARCHAR2(1000);
     v_P1     INTEGER;
     v_temp     INTEGER;
     v_list := '0';
     FOR <some condition>
     LOOP
          v_list := v_list || ',' || <some-number>;
     END LOOP;
     v_String := 'SELECT pID FROM t1'
          || ' WHERE pID IN (' || v_list || ')'
          || ' AND f2 = :1 '
          || ' AND f3 = 1';
     EXECUTE IMMEDIATE v_String INTO v_temp USING v_P1;
