A little advice on my development

[Bionca]

If you want to retain functionality in the penis, hormone treatment will need to be very closely monitored. Going on and off high doses of estrogen can have some complications as the process of hormone replacement puts stress on the endocrine system (liver and kidneys in particular). It can be done, but I would not advise it without a doctor's care.

The other option is to save up and get breast implants and maybe hip implants.

I have no idea where you live, but if you can, I strongly suggest seeing a therapist. This the the key to accessing the hormones safely and getting connected to a good endocrinologist or other doctor to get the hormones. It is also important to discuss issues around socially transitioning and dealing with your feelings and reasons for wanting to transition.
