She She, there are products on the market, that CLAIM to do what you want, to help males grow breasts. They are often female menopause tablets, that can be used my males to grow breasts. I will not mention any here, you can do your own research. Whether they work is debatable. yes there are often testimonials from "clients" claiming they give wonderful results, often with photos. But keep in mind, in the world of AI, these can be faked easily.
Having said all that, I agree with the ladies that posted before me, HRT should be supervised by a doctor as it can lead serious medical side effects (blood clots etc). Female hormones are powerful and lead to more than just physical changes, but mental ones too.. increased sensitivity/mood swings and you actually begin to think in a more female way.
When you transform male to female, you transform in body and mind and there is no real halfway in and you cant always control the results, I will never forget, I was about a year into HRT and my friend and I were talking and then she said.. Noleen you are such a girl, that made my day, yes i did cry a bit.
