Its surprising that wearing an adult diaper has become a fetish for such a large group of people. This fetish is also known as infantilism by many therapists. Some therapists think that it has to do with childhood traumas while others believe it is more to do with control issues. There is a difference in opinion about this, and as there are two trains of thought both can be believed to be correct. The significance changes based on if the people who have the diaper fetish have children. The current train of thought is that people who have children and also Diaper Fetish are in a new subcategory of Fetish Enthusiasts. This fetish, just like many others is very common but the majority of people with it live in the United States. After that the second most common place is Europe. There are annual Diaper Fetish Parties that are held at conferences by a group known as the DPF. As to be expected people travel from all over the world to interact with other people that have the same fetishes as them.
