Crossdressing is an OCD except for those who are transsexual. If this was just a natural part of ourselves we would not need to think about it, or fantasize about it, we would just do it and think nothing of it. CDs also report getting a positive response whether sexual or emotional when dressing. This is an important aspect of OCD which makes it hard to break away from the often dysfunctional behaviors associated with it. This of course does not reveal the reasons why the dressing began in the first place but OCD quickly becomes attached to the crossdressing behavior once it emerges.
