rear entrance 

The ass
The hole at the bottom of the back.
Mainly for delivery of waste, but occasionally used for sexual pleasure

I'd love to enter your rear entrance!

rear entrance 

The ass, the hole in the bottom of the back.
Mainly designed for exits, but some enjoy having things (cocks, dildos, butt plugs) entering it, for sexual pleasure.

I shoved my shaft up her rear entrance last night.

John entered my rear entrance yesterday.

I prefer to use the rear entrance, instead of the front, to be sure I don't end up with a child.
