Thanks for the replies. Being more comfortable and confident does seem like it would lead to being more carefree.
However, how do you know T hasn't built up those traits chemically as well? I mean, there has to be a reason that guys are usually more energetic, rowdy, and adventurous than most women, and that most women are calmer, moodier, and more mature. Do you guys (who said T hasn't changed your personality) think that it's entirely due to social conditioning? (Guys are allowed and encouraged to be that way and girls aren't)?
Personally I think that does have to do with it but I also I believe it has to be due to hormonal differences. I've read about some trans women said they missed feeling like they could "take on the world" (the way they felt on T) but that they happily traded it for feeling calmer, more at peace, etc on E.
I also read that it's hard to be clinically depressed if your T levels are high enough (though this was referring to cis guys, presumably).
Keep in mind that I'm not saying that being energetic and rowdy and adventurous are inherently BETTER traits, they're just the traits that I personally would rather have. I hate it when I feel calm, mature, and serious, although I know plenty of women that have zero problem with it at all and even value those traits in themselves.
I don't always feel that way though, sometimes I genuinely feel like the funny, jokey, ambitious, carefree guy I would rather be, and I'm hoping that going on T will indeed help cement the masculine aspects of personality and fade the feminine ones.
