Rectal temp or finger in the rectum to help with constipation

Does a rectal thermometer or finger in the rectum help with constipation?

Dr.Spock‘s old child care book mentioned using a thermometer to help a child poop If I remember correctly

As far as an older child or adult goes, I would imagine that inserting a finger in the rectum would offer more stimulation to push out a bowel movement. The finger could be moved and rotated within the rectum, while a thermometer would be stationary for the most part

I use my finger with soap to lubricate my rectum to help me to defecate. It feels good with the stimulation to help me relax and eventually defecate

Ok thanks everybody. I've had a problem with constipation the last week but I did put a glove on and lubricate my finger and inserted it. It did seem to work. I did buy a fleet enema yesterday though so that will help it along as well
