Are the shemale born like this?

First the term shemale is VERY derogeratory to almost everyone it applies to. It was created by the porn industry, and is used almost exclusively there.

Now, that that is out of the way. A "shemale" is defined as a person with a female body but male genitals. Prior to puberty only the genitals differentiate between male and female. As such no one can be born a "shemale".

There are basically 2 groups that can fit the description later in life though.

The most common being MtF preoperative transsexuals. The physical changes in this case are induced artificially, through hormone therapy.

The other being an intersexed persons who physically appears male externally, but goes through a female puberty developing breast. This is as close as you can get to being born a "shemale".
