I say who cares what it "makes you." I've never really cared for labeling everyone and everything. But I would say that if you are having these urges talk to your wife about it. If she supports your crossdressing, there may very well be a part of her that suspects you have such urges. Maybe you can find support there, perhaps shared fantasies or something of the like. Certainly don't do anything behind your wife's back, that will only end up hurting the both of you.
