BM-04 - In 2006, a member of a German forum calling himself Amanitus shared his experiences as a boy.

“Not everything that is criminal is punishable and not everything that is punishable is criminal.
When I was eight to nine years old, I got to know a man with whom I soon developed a friendly and sexual relationship. The relationship with this man went on until I was twelve or thirteen. I was very happy and proud because of my early sexual experiences and I continue to be so.

It's more than 35 years later. Only later on I was told that this man must have been a pederast. 
The sexual relationship I had with him at first remained a secret, but it was very important for my coming out as a homosexual and my gay development. I mean, nowadays, nothing better can happen to a gay boy than to have a relationship with an older person who shows him how he can get pleasure from his body. Back then, I had my first (still dry) orgasm and I experienced how great sex with a man can be."
