Femme,
The thing with BO, everyone is different, so what takes one person years may take another months and some never get anything from it. You did hit a key point, body temp is key with BO.
Yes pelvic discomfort is one of things you want, if you are going for overall feminization, if that's not the goal then a person should probably back off on BO at that point.
It's reported that, with the exception of breasts and possibly infertility, the effects of BO will reverse after an amount of time off of it comencerent with time on it, and others have told personal accounts of never being the same after taking BO just a few times.
