Feeling of Tightness/Fullness in Rectum?

Hi. At your age you can probably rule out it being any serious illness or growths. Sometimes if straining has occured it can cause the fullness feeling. Have you been inserting anything into your ? Sometimes masturbation causes unusual feelings too. One possibility is that a rubber glove has gotten stuck up there. Nurses often use rubber gloves and it's possible one is actually retarding the flow of your faeces from your rectum. Good luck with this. Remember if you are going to practice or use of rubber toys always use lubrication.
