There is no such thing as intersex. Kalif has DSD, he probably has an extra X chromosone so he is XXY, BUT it is the Y chromosone that results in a male pubery. He will produce testosterone like any other male along with a male physic.
As a baby he would have had ambiguous genitalia, however this is a secondary sex characteristic. As puberty hit it would have been obvious.
If you have a Y you're a guy...
