Honestly, I think I'm the same person today after 535 days of testosterone as I was before it, for the most part.
Obviously I've changed some, everything changes at all times, but I do not attribute these changes specifically to testosterone.
I still feel the same emotions, but the effect of the emotions is milder, more controllable.
I get just as sad as before when sad-causing-events come my way, but I don't sob uncontrollably.
In fact, I very rarely cry, which is wonderful, considering that just being "very tired" could be enough to make me retreat to bed where I'd curl up and cry for a while without any chance of controlling it at all.
I am also calmer, generally happier, MUCH more content and comfortable in my own skin, but I don't think that's because "T" makes me experience this per say, more accurately I think that the physical changes caused by T have made my skin fit "me" better and therefore I'm calmer, happier, more content, comfortable, etc...
