i always felt kind of a woman

You don't need any silicone to be a woman. You don't even need hormones to be honest, although that's a way to get breasts without any surgery.

What is it that makes you want to be a woman? I'm sure you've been thinking about it for a long time but a little more info might help people give you advice.

If money/insurance permits you could seek out a specialized therapist.

 

Well, you don't really "become" transgender.

There are lots of ways to transition, with or without surgery or hormones. You can transition without changing your body at all. You seem to have an idealization for getting breasts which is understandable, since it is one of the things people can easily see and think female.

Perhaps it would be best to seek therapy/counselling, as that will be you're best way to work out what your best options are and also to work on how you feel with someone experienced in working through this with people.

Do you feel any disconnect when thinking about yourself as male? Are you uncomfortable with certain parts of your body? Do male pronouns make you feel put off? I'm not doubting you are trans but these are things worth thinking about deeply before rushing off to transition.

 

I'm not saying to pay someone to tell you that you're female, they can facilitate the process of transition. Granted I'm not sure exactly how it all works overseas compared to where I live. Some place require a letter to start hormones, which is where you'd have to start if you wanted them.

You don't need to change your body to transition, you can wear female clothes and do nothing else and still be female. No one who transitions is really the same, some people are more comfortable without any surgery and some are, it's the same with hormones and honestly even clothes. It is a very individualized thing. Some people eventually get SRS and some don't, you don't need to do any one thing specifically to be trans.

It is worth discussing more, I'd imagine. If you accept your body as male you definitely need to flesh out your feelings a bit more before rushing into transition. The one driving force of transition is that you cannot live with your body how it is, for whatever reason, some sort of disconnect is there.

You mentioned in your first post that you identified as possibly bigender. It seems that may still be the case and you are wanting to feminize your appearance even more, which may seems to be more accurate if you're totally accepting of your male body.

No matter what the case you'll need to see a medical professional of some sort if you'd like to transition physically. This is why I'm suggesting a therapist, not to tell you what you identify as but to start the process of transition since it is generally where you'd go to start. Perhaps there is an LGBT center near you which you could call to get some helpful resources on where to start.

 

You don't need hormones or surgery, you can dress female without breasts, lots of people do it. You can stuff your bra, leave it unstuffed, use breast forms and I'm sure there are other options out there that escape my memory.

Without surgery, hormones or breast forms your only other option is stuffing a bra as far as I know. You don't need breasts to appear female, many biological females are quite flat chested and there is nothing wrong with that. If you want physical breasts there aren't really many proven options outside of surgery/hormones, unfortunately.

If you're wanting a more female body but too scared of hormones and surgery your best bet is exercise and diet, it may have limited effectiveness based on the individual but that's a way to change your body on your own with no medical intervention, assuming you diet and exercise properly!
