I basically have no Adams apple since I have gained a bit of wait but I think the best way to hide a small one is to take exceptionally good care of the skin in that area and you will see over time that it appears faded or it kinda blends in better. This also applies to hands and feet, or even a nose

.
To me skin care is one of the biggies when it comes to making yourself appear more fem. So constantly use micro dermabrasion's alpha hydroxy's and vitamin E right out of the gel cap 400iu. And rough areas will smooth out.
this also has to work with your skin type. Mine is on the dry side!!
Hope that helps
