I have replaced the same O2 sensor twice and now the same PO136 code is coming up again. What are the possible causes losing the same sensor in a short amount of time?

That would be a code for the sensor after the convertor. Its not really a big problem, basically if the new one didnt help chances are the catalytic convertor is not functinoning properly. Or you have an exhaust leak.
