First, you probably mean the rectum, which is inside the body. The anus is the opening to the rectum. But.. You can't make the rectum 'longer'. It's like asking, How can I make my finger longer? or asking, How can I make my nose grow?
The rectum like the anus can be stretched in width but not lengthened.
Important--- The rectum and anus can be permanently damaged. That damage can result in constipation and leaking of softer stool.
