Okay, I hope this is the right board for this & that it's not inappropriate or something. Umm, uhhh.... this may seem a bit unusual, and I may be jumping miles and miles ahead of myself (as MTF/TG, I am still 100% "in the closet" so far. and I dunno how I'd be able to afford transitioning anyway. It all still feels like a dream & possibly unattainable). But, I still want some answers to ease my mind.
I'm a little concerned about how my breasts would develop. At first, I didn't really want breasts at all. But now, after thinking about it, I think it would definitely be pretty nice! However, I still hope that they wouldn't get really big. Just... average, I guess. I mean, I wouldn't want them to attract extra unwanted attention from being really big or something. I guess whatever happens, happens though. I am also concerned about how they might look as I get older, whatever size they turn out to be. I... um... I'm sure I'm not the only one that fears this, but would they become saggy? And would that be even more likely as I age, the bigger they are?
I am kinda worried about breast cancer, since it seems to be so common in the world. I guess I shouldn't worry too much though. I don't think many women in my family have had it.
(Meh. Getting old is going to suck no matter what, but I guess we all just have to deal with it. *sigh*)
Here's another question. I fear a doctor is the only one who could really give me an answer though. This is kinda embarrassing too. I have what I am very sure are lipomas, which are entirely benign, fairly small, non-cancerous tumors that form on my body under my skin. (Most are in my arms) If not, then they might just simply be cysts, which are usually just as harmless. My question is.... would taking hormones have any effect on these? Would it make them able to possibly become cancer, which is next to impossible for cisgender people?

Or, here's a good possibility... could the hormone changes in my body actually cause them to go away? That would be nice.
Umm... uh... more embarrassing stuff.

How about my unwanted male parts? Will HRT help me lose the urge to masturbate? It's weird. I don't really like masturbating, but I think I'm addicted or something. I can't stop myself from doing it every so often. I can stop for a few days, maybe a week, but I always go back to it. I know it's physically healthy for my body, but it feels weird & wrong because I am so insecure about having male parts in the first place. (though it's probably normal for cisgender guys to masturbate often, probably even more than I do) Also, will HRT stop unwanted erections? Pretty sure it does, but how long would that take? And "stuff" will get smaller, right? There is little to no increased risk of cancer in the testicles or prostate?

Oh... here's another question. How would I take estrogen, spiro, and whatever else (is there anything else?) anyway? Would they be pills? That would probably be best. However, would it slowly start killing my kidneys or liver or something?

Wha about patches? That might be okay, as long as they don't have to be worn 24/7, I guess. Hmmm... um.... I am not entirely afraid of needles, I can handle shots sorta, but it would really 100% completely suck to have to inject myself with HRT stuff every day! I really hope I never develop diabetes. Sadly it seems to be common in my family. Especially for the women
I heard a rumor that you can't take ibuprofen if you're doing HRT. Is that true?
I have this fear that transitioning would shorten my lifespan, or something. That's not true, is it? Don't transsexuals live just as long as cisgenders? Plus, wouldn't the stress relief of transitioning effectively increase my lifespan from what it would have been? (like from the stress of "being a guy" and not transitioning... would that not lower my lifespan to some extent? I would actually live longer if I transition, right?)
