No. But here you said, "for my entire life". The act of crossing is not necessarily permanent. Think of the word, "transcend". To go beyond. It can be just sometimes for a crossdresser, or it can be all the time for a transsexual. (Well actually, a transsexual does not "cross" anything in my view, since she is already a woman.) But, if your feminine presentation is no more than a costume like you do for cosplay or halloween, then I see your point. It's like a grown-up version of playing dress-up as a child, and that's OK too.![]()
The first definition in your link is the google summary definition that is designed to be a brief as possible: "Adjective: Identified with a gender other than the biological one." But, directly underneath this definition you see four links to further explanations. One of the links is the definition from Wikipedia that I use all the time. It says, "a general term applied to a variety of individuals, behaviors, and groups involving tendencies to vary from culturally conventional gender roles". The Widipedia article is more in-depth and it draws its content from 160 sources listed at the bottom of it, from experts in the field. The other three links directly under the google one-line definition lead to web pages that also have one-line definitions and that don't cite their sources.
I'm just saying, you should you get your information from sources that discuss this in more than one or two lines and not from the quick and easy web sites, simply because the issue is so complex.
