First of all, I quiet don't know if this is the right forum to post this thread because it is a bit DL related, too.
When I hosted a munch in Germany I got in contact to a person who is way older than I am and had searched for reasons of being the way he was a lot longer than I had.
He started to busy himself with this question and the look for scientifical journals that dealt with this topic in the early nineties.
By now the only journal that deals with the topic of psychosexual infantilism that I know (from him) is "Patterns of Psychosexual Infantilism" by Wilhelm Stekel.
When I started university almost 2 years ago I realized that the acess to science searching engines could help me to find more. Being almost the same age that the friend was 20 years before, but I wasn't lucky.
The only thing I found was a journal which was about a couple that had problems because of his fetish and how to deal with problems in a relationship where one has a fetish and the other one doesn't. It didn't go into detail why he was that way.
I'm wondering if anyone of you knows science articles that are related to the topic and which are less than 40 years old.
Thanks a lot
