I think his father Bacha Bazi'd him as a child. That's the Afghani Muslim way.
From wikipedier:
"
Bacha bāzī (
Persian: بچه بازی, literally "boy play"; from بچه
bacha, "child", andبازی
bāzī, "game") is a
slang term in
Afghanistan for a wide variety of activities that involve
child sexual abuseand
pederasty. The perpetrator is commonly called
Bacha Baz (meaning "
pedophile" in
Persian). It may include to some extent
child pornography,
sexual slavery, and
child prostitution in which
prepubescent and adolescent boys are sold to wealthy or powerful men for entertainment and sexual activities.
