The amount by which her dick has shrunk from around the time of her early porn until now, and especially recently, is pretty noteworthy. Maybe those pictures from her most recent picture set give an exaggerated effect and she's not quite fully hard, but it looks about two inches shorter, if not more.
I have to wonder if it's deliberate. She has to know her big dick helps sales, and she has to know that if she's planning to get SRS, maintaining size is important too. Maybe it's a consequence of her exaggerated hormone cycles. A few years ago, she was obviously taking less (or no) hormones and was very functional and toned. She's since switched to a much more feminizing hormone cycle, and maybe haven't taken the right supplements to avoid shrinkage.
