Hi, redhot1,
It isn't necessary to start out by cross dressing, but it wouldn't hurt, either. I started by cross dressing, but I wasn't filling out the bra. So, I took steps to enhancement the boobs and now I even took steps to get more of a feminine shape, as well. It all takes time. Just think how long it takes a genetic female to develop fully! I also like women a lot and would love to look just like them. Well, maybe with surgery.
