I just wanted to share this story that happened to me this past Friday night.
I had started HRT on 10/11 of this year. I had also asked (in this forum) how long it took before my nipples would start to hurt. The answers varied from 1 week to 2 months. I figured it would be 1 month before I experienced the "pain.".
Now to the story:
I woke up Friday morning (10/27), took a shower and went to work. In the shower, I felt my nipples, which had been getting erect for app. 1 week. I thought I felt a tenderness, but didn't think anything of it. During work, the tenderness stayed with me.
After work, my S.O. and I always go to the same bar in the neighborhood to unwind. After 1 or 2 drinks, I completely forgot about the tenderness in my nipples. A very good friend of my S.O. (and mine) showed up, whom we hadn't seen in 2 months. She is also a little bit open in her morals and dress, and was wearing a very loose top. She also has DD boobs, so a good portion was showing.
Anyway, she made a comment about possibly getting a nipple ring. I commented back that I would never do that because it would hurt too much. At that point, she reached out, grabbed my nipple, and squeezed and twisted it

YOU TALK ABOUT PAIN. I tried to keep a straight face, but wanted to pass out on the floor. Yes, they ARE more sensitive and hurting alot more.
I also believe I have started to develop. My (soon to be) boobs appear a little more swollen. This friend of ours (after squeezing my nipple) also made the comment that "YOU should get a nipple ring because your nipples are big"). That's the first time anyone made a comment like that to me.
Anyway, I'm getting excited.
