I'm sure that the scientists would love to be able to "prove" that people born with the birth defect of transsexuality are merely extreme cross-dressers, but unfortunately for them, the fact don't fit with their hypothesis any more than they fit with Blanchard's half-arsed attempt at pseudo-science however much credence a few members of this site give him.
There are some gender variant people who suffer from a mild form of Gender Dysphoria but who are not transsexual. Those people need and respond to a combination of therapy and in some cases hormone therapy, but from what Tink says, her husband does not fall into that category either.
Tink, if your husband is adamant that he loves being a guy and has zero Gender Dysphoria and zero desire to be a girl, I think you can accept that he knows what he is talking about.
