I tend not to. The only time I ever do is if I know I played bad due to silly unforced errors and concentration issues. If I help myself lose the match, I will stew about it for a bit and try to figure out what was causing me to not execute.
Don't get me wrong, I do like to win but losing doesn't hurt that bad if I can learn something from it and work on it.
