Just a word of caution. Ive seen this mentioned a few times by different guys on the board. I know we all have our opinions about surgery and trans folks.
My only advice is don't use implants and surgery as the litmus test if you are. Between hormone therapy and a few changes in habbit a trans person can grow their own natural set of breast, lose unwanted body hair, or get supple naturally feminine looking skin. If this a big concern for you, you may have to look for things like bone structure, wide chest and sholders. Disproportionate hands and feet for her size. Adams apple can be tricky because we actually all have one but not everyones is pronounced. Men tend to have larger ones obviously but women also have them they just arent normally as pronounced. Vice versa for some Men and small or non visible Adams apples. Its just a matter of how the larynx develops around the thyroid so any number of factors could contribute there. In any case, Ive been seeing this mentioned so much more than usual lately. I can't imagine people haven't had these concerns before but it just seems to be coming out in peoples posts alot lately.
