[spanky (aka Lola)]

I second Jannet's comment, especially her final one. Addictive is a perjorative word, but it is pretty close to capturing what seems to happen. I started partly out of curiosity, with a desire to have munchkin boobies. After a while, it became a lot more important to me and stopping at tiny was no longer my plan. Going much further began to feel right. I think quite a few people have had a similar evolution in thinking.

To be honest, if it's just a kink for crossdressing, buy your self some breast forms. You can position the forms to push some skin forward and up to give the illusion of breasts.

Most fat that migrates to your chest will eventually disappear once you stop, any real breast tissue ( milk duct ect ) will not. Unfortunately, your body is preprogrammed for a size and shape of breasts, until you start your not going to know what you will get.

As noted in previous reply, it can get addictive. It may change your thoughts so much that after a while your thinking of transition.
