I've been on HRT for about 9 months now, and while I have noticed an overall reduction in body hair (and its rate of growth), there are a couple of areas that are still close to previous levels...
The knees (+/- 3"), and the elbows (+/- 3").
It's just strange, I guess. Just wanted to share.
On a positive note (on a different area of the body), I've learned that if one removes the pubic hairs except for a border of about 1"-1.5" around the primary organ, that helps to create a more feminine look to that area, especially when viewed from the corner of the eye.
