As a child, did you play with your anus or put things up it?
I used to like having my temperature taken in my rectum. I would ask for it when my mother would take me to the doctor. Later I experimented with putting things up my anus, like pencils and enema nozzels. I would like to hear others' experiences about this. Did you develop an anal fixation when you matured sexually? (I love enemas and colonics!)
