It appears to me that there are two entirely separate and unrelated issues here.
There are sexual issues that society has said are subject to exploitation, those involving minors and an adult. Whether or not that's a resonable position is open to question and debate, but it is not an issue related to religion.
Then there is a laundry list of items that are a problem only if religion is brought into play. There is no reason other than religion for anyone being bothered or concerned about homosexuality, multiple partners (as long as they are informed participants), multiple wives, adultery, fornication.
