I don't own either Desire or Fleur de lis Desire, but I have Bliss and FDL Bliss from the same company. I also have FDL Silky G and FDL Delight. The Fleur De Lis line is made of silicone. They are very flexible-too flexible for me. They just bend too much against my body to be enjoyable. Of the three that I own Fleur De Lis Delight is the best. It's shape is a bit more solid so it doesn't bend as much. I am not sure how FDL Desire would be.

Evolved also sells the same designs in plastic. Bliss is the only one I have of these. Plastic is of course a hard material. I like it better than the silicone version because I can get the pressure I need. Plastic is still easy to clean.

Your enjoyment will depend on what your body likes. I need pressure so too much flexibility doesn't work for me.
