Hi again Funnygurl,
Weights won't bulk you up if you use light weights with lots of reps. Ask a trainer for a programme if you're worried. Personally I would concentrate more on cardio - e.g. cycling, walking, running, swimming....
My question to you is what would be your desired end point in all of this? Are you a transexual wanting to transition, a cross dresser just looking to be more feminine? Do you want to pass as female or just feel more feminine? Do you feel dysphoria? Are you a male inside, female or something else?
These are serious questions as I think the way you go about changing yourself depends on what your desired end result is and how much discomfort you have with your birth sex.
I think I read in your introduction that you want to be more feminine, and your profile says you identify as having male gender. You said you are new to all of this. What this says to me is that perhaps you need to do some more investigating before jumping into anything you will regret later. Hormones are not things you take lightly. They will change your body in ways that are ireversible and can be a major health risk (blood clots, stroke, organ failure to name some..).
There is no reason why you can't start dressing now in private. At least this is an easy way to start exploring your feminine self and find out what you really want. Don't let weight stand in your way, at least it is easier for you to create your own clevage. My advise is to talk about it, read about it, meet other TG people, go to TG groups, maybe visit a councillor or gender therapist.
Happy trails..
