Hun, don't let the hype fool you, there is no "natural way" with out effecting the bodies hormonal balance. Herbs typically don't work for most people. If they do, they will have an effect other parts. Not just down below, but the liver, kidneys and cardio system by way of raising or lowering BP.
This is fact even for TS that are going through HRT through a Dr.
Also consider this, straddling the gender binary is a hard life. If you ask around the trans section they will tell you, I myself have been a helluva time doing so.
This part is my opinion, do with it what you will. I want not to sound like someone cramming their baggage someone else's throat.
If there was a way I would have myself a pair of b/c's already which would make my passing a lot easier. (Still waiting for my HRT letter)
