When I did volunteer work for HIV/AIDS I worked with a few male to female transgenders in varying stages of transformation. Their body changes as they take female hormones. You'd be surprised what these hormones can do. Their hips enlarge, they grow breasts, their muscles shrink and their figure becomes more feminine. About the only thing that doesn't change is the adams apple.
These people aren't freaks doing this for fun... their gender identity has been screwed up from birth. Most started identifying themselves as girls at a very young age. The pictures Fastball showed here are ones who are very "passable." However, many times the transition is not so successful, and it's obvious they were once men. For these folks, life is very hard and employment is quite difficult. The sex industry is often times the only thing they can do to make a living. It's quite sad, actually. More then a few end up with HIV/AIDS just because they need to pay the rent and eat.
In fact, if I'm not mistaken, most of the transgenders Fastball showed work in porn. It's rather obvious by the makeup, lighting and style of the pictures.
