No not your imagination. After 18 months on HRT, with 8 months on full transitioning dose, I have quite a nice rounded cheek bottoms and I have added 2.5' to my thighs as I discovered recently when I split three pairs of men trousers two from the waist on the hips to the knee when I bent over (the seams split).
Now my women's jeans at the Hips and bottom are starting to be a snug fit and finally showing off my curves. I just wish I could lose more weight at the waist line. Luckily though my boobs are now starting to be bigger than my tummy thanks to how pointy my nipples have become (very erect all the time!)
