(Sorry, it's been a hectic couple of no-internet-vacation-like weeks, so I haven't been able to reply.)
I'm going to put my two cents in and I'm going to say that it was most likely my pre-transition anxiety, as I am going back to school as male this year. I say this just because the last time I felt like crossdressing was when I wrote this topic, and it hasn't really plagued me since.
Also, I was in fact only crossdressing in the safety of my home, so as to not to be confusing.
Now I'm just feeling a lot better about my previous... "urges" to dress as a woman, and I don't think I'm going to crossdress any time soon. =)
Thanks so much, everyone, for saying something about this. I'd honestly never heard anything about FtM crossdressers.
