I wanted T to make me more social, more confident, but it hasn't. However, I knew that it probably wouldn't when I took it; I just thought that, with a body that I was more comfortable with, when I eventually did begin to work through my problems I'd be better equipped. I still think that is true; I am already better equipped to deal with my issues. But in a sense, there are more issues. Before I started T, I had this sort of fatalistic view that people would see me as female and I'd just have to deal with it; I never stood up for myself, and I sort of felt like I didn't deserve any better until I looked the part.
Now, however, I'm still having troubles passing. I think I've just got one of those "baby faces" that will take time to change, seeing as all the men in my family were mistaken for girls when young (bwahaha), so I am absolutely fine with waiting. However... Now, I don't take ->-bleeped-<- from anyone. And that makes life a lot harder. I think I deserve more, so I am more bothered when those slip ups happen, or when I get read wrongly. All my old problems are still here; I just feel a little bit more centered, a little bit more comfortable, and on the road to more of that. It is a long process.
I've always had bad acne, and it has just become a part of life. We all have to adapt to those things. In fact, most teenagers get acne, not just guys. It's not like we can pick and choose these things. I had constant acne prior to T, and I have constant acne after T. However, sometimes it's actually better than it was... But at this point, it's really just about "maintaining" it so that it doesn't get horrible. I am okay with that. No one wants cystic acne, no one wants to have to go on acutane or an antibiotic. Everybody hates acne. But everybody also hates cancer, and baldness, and being too short or too tall, or having a funny nose. Part of being human is accepting imperfections and things beyond our control. Just be glad that this in your control: you can choose this, a male puberty that will change your body in ways that you (hopefully) want. Or you can choose otherwise. However, that is within your control.
As for downstairs growth... I can't exactly empathize because I was always really excited about it (and have always just wanted more and more), but I didn't feel uncomfortable or anything. I personally didn't feel pain or discomfort from it rubbing against my clothes. My sex drive isn't "out of this world", either, but I kind of wanted it to be. Then again, I've always had a low sex drive. Everybody is different, and like everyone has said, you just have to accept that.
There are tons of men and women with more body hair than they want, more acne than they want, a higher sex drive than they want... And they live. And it goes the other way, too. There's really nothing anyone can say to change your mind either way... And you shouldn't let other people, either. But you do need to be certain in yourself. You either have to be willing to go all the way, or not at all. That is what I think.
The scary thing for me was always that I'd be rediscovering myself, and learning things that I didn't know before. It's really an identity upheaval in some ways. For instance, being a short, balding man is quite different from being a short, androgynous boy. That does change the way you are perceived and the way you perceive yourself. But at the same time, you are still you: you can still change the way you are and the way you are perceived. You won't ever be like "every other short, bald guy"; you'll just be you. Except with less hair. Tons of men go through this all the time. In fact, life itself is a constant metamorphosis, when you think about it. We're always changing, even cisgendered people, and often in unpredictable ways, due to forces outside of our control ... But yet again, every human has to learn to live with this.
In the end, you will always be you. Accept that, embrace that, and learn to work with what you have been given.
Good luck, and I hope you figure this out. It's never easy.
