Read William Shirer's seminal work "Rise and Fall of the Third Reich" - at least in the chapters involving the SA (commonly known as "brownshirts") who were indispensable for getting Hitler into power. Be forewarned though: Shirer wrote most of it in the 1950s, and frequently uses the word "perversion," a commonly understood word back then, but one which can grate on tender ears born after the 50's that have only heard euphemisms like "alternate lifestyle".
You can also google "Ernst Rohm", the SA leader and #2 or #3 Nazi, until Hitler executed him and the rest of the SA leadership (a preponderance of whom were homosexuals) in a Machiavellian bargain with the German Army leadership, soon after the SA had vaulted him into power and he no longer needed them, but at the time desperately needed the loyalty of the Army.
Of course, anything from Wiki or other mainstream or liberal web sources is going to have the SA's sexual proclivities heavily played down. Better to buy a book on the subject - eg The Pink Swastika
