I bought my aneros in my 20s. Had a lot of good sessions over years. Now in my early 40s I’m wondering if our bodies change enough to request an upgrade of the device ? … I realize that the last couple years were different. Feels like my Aneros isn’t massaging as it use too. Does anyone had to update the model with time ? Do you think I need a bigger head or longer one? If you’re in your 40s and have great sessions with a device, please let me know which one! Thanks for your advice!
