Yes,basically the idea is,there would be a whole in the mattress to pee in,in the middle ofthe night so you don't have to get up.You put your penis in the whole and pee into it,and it is a pipe that leads elsewhere.It is not for anything sexual,only to pee so you don't have to get up. I don't understand what is so gross about this. It would have a little cover like a mini toilet seat.And inside plastic tubing.The pee goes to a container elsewhere wjhich can be emptied out.You can easily clean the tube. No,the mini seat would protect the sheets from getting wet.And inside is a plastic tube that leads to the pee container. It is sanitary. Your not listening. It is a PLASTIC TUBE INSIDE THE MATTRESS, NOTHING GETS WET OR COULD POSSIBLY GET WET UNLESS YOU MISS THE HOLE.PUT YOUR PENIS IN THE TUBE AND PEE,AND IT LEADS TO A CONTAINERTHAT IS SOMWHERE ELSE.
