Under Sharia, before boys grow pubic hair, they don't count as men, and sex with them is permitted.
Muhammad established this rule, to mollify some of his recruits who preferred this (all the heterosexuals were getting to rape the female slaves they were taking as a reward).
Ever since, boys for sexual use by men has been a significant part of the muslim slave trade within the muslim world - and muslims have been the dominant force in the global slave trade for almost their whole 1,400 years. Most of the slaves sent to New World were purchased at muslim slave markets on the coast of Africa.
Pederasty (male homosexual pedophilia) remains widespread in islamic areas today which is why Michael Jackson fled to Bahrain for a while, to a pleasure palace with lots of boys. If you have a strong stomach, you can look up Bacha Bazi (boy play), still popular in Afghanistan and Central Asia. My understanding is that in practice, homosexuality is more widespread among muslims than we are accustomed to (especially pederasty), but is undercover.
