When I was trying to find a solution for myself I would come upon websites that dealt with curing crossdressing desires. At the time I felt that I needed to heal from what I determined to be a curable abnormality. I sincerely believed that such sites could be helpful and provide inspiration. Ultimately they weren't and my understanding today that I am a borderline transsexual has completely changed my mindset on this issue.
I occasionally still come upon a site that proposes that one can be “cured” of the affliction of crossdressing which only gives me visions of some young transgender kid ending up there and not finding what they need. A sexual addiction is not the same thing as being transgender.
If one began to crossdress for the purposes of sexual gratification then its very likely one can stop because the dressing is not tied to identity. If it ultimately winds up causing distress then this is a significant sign that there might be a problem. However in general, transgender and transsexual people find relief by crossdressing.
I remember being very concerned about Catholic doctrine and so years ago I consulted a Monseigneur who told me it was at worst a morally neutral issue. But then he also reminded me that crossdressing is a verb and not a noun and that there was more to me as a person than whether I crossdressed or not. I never forgot that.
It is not uncommon for some transgender people to go through a phase where they identify as a crossdresser. This can sometimes help remove some stigma and avoid a potentially bigger question of whether there is something more to their desire to crossdress.
As for those who have successfully cured themselves from what they consider to be a sexual addiction? they are to be congratulated. But we are not all the same and we cannot be painted with the same brush.
This blog has always advocated the idea that transition should be a last resort and there are ways to cope with gender dysphoria. Crossdressing may just be one of those tools that works.
