Methinks my method might be slightly unusual, but it is born from the fact that I've never really had that much down there to worry about. Basically I pull everything up, not down. While the two roundish things then slot neatly into the intended sockets (and HRT has made them shrink enough for them to no longer show up in any way), the middle element is flat against the body, held vertical by virtue of, usually, a pair of AA unisex briefs and a high spandex women's panty (left / right movement is sufficiently inhibited by local hair). Forms a small mound, but nothing major, and essentially vanishes under the zipper when wearing skinny / super skinny jeans, with no external signs. No tape, no toilet issues.
That being said, the method works with pretty much everything except for pencil skirts. Those are an entirely different beast.
