I think you mean Ernst Röhm. Röhm was Hitler’s right-hand man as head of the Sturmabteilung (SA, the Brownshirts).
But I wouldn’t be surprised about the SS.
Nazi homosexual rape (especially of young boys) by SS of prisoners was extremely common — and encouraged.
I read the transcripts of the Polish war crimes trials in my undergrad days in college; what stood out to me was the assertion that the SS was riddled through with homosexuals; the first thing the SS would do when they came into a town our village was to look for young boys.
The Poles found this so repugnant that they executed any boy or man that was corrupted in this manner.
It was. I think one of the initiation procedures for the SS involved homosexual rape. It was designed to make these men submissive and loyal to their commander.
Disgusting, but it has been used in other societies, such as the Spartans.
Male rape is all about dominance.
