It's like everyone says, very difficult to predict. My partner one day had to call my younger brother (he's 22, I'm 26) and ask him something for me, and then call me back and tell me what he'd said (I was in the middle of getting a tattoo, so I could only talk for a bit) and my partner said he had to check the phone to make sure he hadn't accidentally called my brother back. I'm three months and like, two weeks on T, and this was three weeks ago. It's only gotten deeper since then.
