I have it, have had it for as long as I can remember. Starting HRT did not change anything until 11 yrs in when I noticed it was much, much less...almost gone. I don't know if this has anything to do with my change in HRT around that time, going from oral estrogen to injectable estrogen and/or progesterone. My dad HAD the same thing and he said that with time, it just vanished. Maybe it's somehow connected to the level of androgens as my testosterone is also the lowest it's ever been.
