If you really need to have a label (some people do) then how about this - you are uniquely you and will constantly develop as you progress down your journey of self-discovery.
The key words are unique(ly), develop, journey and self-discovery.
The advice that goes with them are be true to yourself and be as truthful as you can - especially when discussing this subject with loved ones. You will never know what you actually like unless you try.
Admiring girls such as Davina or whoever is fine, but try to discover yourself rather than making yourself into a "clone" of someone else. This can be a highly personal thing for many of us and some find that the initial sexual aspect diminishes as they progress to dressing more frequently. The majority are straight (when applied to their birth gender) although some are not and with others their preference stays constant whether they are in either persona - so don't worry too much about any pre-concieved ideas or fantasies, these are normal and may be an assertion of what your actual gender mix is (there are very few people in reality who are 100% male or female - all humans usually have some degree or other of both genders in our make-up).
One last point - if it feels right then it usually reflects how you feel at that point in time - with some the urge is constant (which can be frustrating if opportunities are seldom) but others follow a more cyclic pattern where they swing between dressing and not dressing (the latter can be due to guilt about dressing, convincing yourself it is wrong or simply that the urge isn't there).
The only strange questions are those you wouldn't ask yourself to answer and the only stupid ones are those you don't ask (stupid because you will never know the answer if you don't ask). Even if it seems a simple question, for example "Is there an easy way to put a bra on?", you won't be ridiculed for asking as there are probably many out there who struggle to do this without getting frustrated.
"Denying who you really are, only leads to regrets later in life. Seize the moment because it will never come around again."
I have been reliably informed that I am a much bigger bitch when I am NOT Sara!!!!
