I think that you are right in that there is a difference between the two,
most can look like a woman if they had enough time and maybe money and practice to create the illusion that is what you will see on the out side.
But being feminine is something that has to come from the inside, it is something that controls your hole body, movements and thoughts, the way you stand, sit, walk, jesters and movements with your hands, soft flowing motions, and because of the different muscle tissue in a male it would mean that you have to put a lot of time and effort into it and it would not be something that you could switch on and off at will, so if you can achieve that i think it will be something you will show all the time without you even realising it .
Then if you reach that stage and wear something soft and feminine you will flow like a gentle breeze in the long grass and be the envy of all .
