I am just a couple days away from 3 weeks on HRT and today my nipples are so sensitive as well as getting larger.  I have been in a meeting most of the morning and the air conditioner is super cold in this room and I have two things that are telling me just how cold it really is.

Guess it is just part of the ride.  Thought I'd share with you all!!!!!

yes, welcome to the ride.  Keep a diary of your experiences, you will be glad you did

Get used to it. I'm 8 months in and mine still hurt
