First, sorry iaboy for contributing to the hijacking of your thread. I tried to not to but I guess I lost that battle. I felt really bad afterwards cause I realized I hadn't even contributed to the original topic at hand.
I'm not sure what the driving force was in the beginning. Part curiosity, part desire, not really sure. I know I admire breasts, and as far back as I can remember enjoyed playing with my nipples. Perhaps part of me wanted something a little more to play with ha ha.
The idea of transitioning for me is just not practical. There's several reasons like, family, work, not really passable, etc. I think the main reason for me, is that I don't really feel feminine, and I don't really feel manly. I am stuck somewhere in between. I am a blend of male and female characteristic traits. Sure I sway a bit more on one side or the other at various times, but for the most part I walk that fine line between both.
It took some time for me to realize this, for in the beginning I wasn't really sure what to expect or why I was really doing it. I guess I was playing mad scientist with myself and experimenting to see what cause and effect this all would have on me. Now it's a bit clearer, and I am much happier with myself. I am shaping my body to match how I feel inside, a blend of both male and female characteristic traits.
