This is pretty much my omg-what-will-happen-to-meee list, for when I start HRT:::
1) Pets! Do your family pets, cats especially because I have two cats, treat you any differently?
2) Weight distribution, for FTMs, HIPS. I am worried about my hips, because they are quite wide. And the men in my family don't have hips like this, just the women. So that does mean once I start on T, my hips will down considerably?
3) Acne. In my entire life, I've never ever had a problem with acne. Even through puberty, it was a barely-there sort of thing. And I've read that HRT is like going through a second puberty, so will the acne be about as present as it was, or much worse, or?
4) Hair growth. My brother is not hairy at all, he's 31 in August, and he can't grow chest hair at all. My leg and arm hair pretty much doesn't grow. I haven't shaved my legs in almost 7 years, and it's just slightly prickly and you can't see it at all, because it's so fine and blond. So, on T, will I even have any sort of body hair?
5) Existing medical conditions. Because I have rosacea and trigeminal neuralgia. And I'm a little worried that T will make it worse? Though, it might make it better. But I'm adding it in, in case any of you have the conditions, and you could give me your experiences

Obviously, I don't expect you guys to give me absolute definate answers, but your opinions based on what you know, and what's happened to you.
