I guess I am dense because the first thing that stood out was the use of the word "bottom".
They use the technically exclusive term "Bottom Surgery"
which is not the "bottom" it is "Dick" surgery (another scientifically technical term)
in order to create the artificial appearance of a "front hole" (another scientifically technical term)
Bottom, Dick, front hole are all now scientific terms
and, BTW, if you read it carefully, using your great INTJ powers, you will understand that a "Dick" has straps for attachment.
and a "strapless dick" is actually what used to be know as a natural male penis.
Man I am really getting slow on the uptake
