Tips on lowering testosterone for a "femboy in training"

So I've recently come to really embrace my feminine side, and decided I'm going to do my best to become a "femme boy", which has always been a sort of repressed dream of mine. Now, I'm not really super masculine in the first place, but I would like to promote a little more of an effeminate look- other femboys have told me to try and lower my testosterone. I tried looking up how, but there's very little information about it except for transgenders who are transitioning through drug therapy, and that's not what I want. Can anyone advise me on what to look for? And on that note, any additional advice for a newbie getting into this stuff?
