I have liked to crossdress since I was very young. Didn't actually go out dressed until I was in my twenties. I haven't gone out dressed in the last 17 years since our first child was born, and hadn't actually done much "full" dressing until about six months ago. Now, for some reason, the urge has come back very strongly.
I don't know what precipitated it. I think maybe the light at the end of the tunnel WRT raising kids... I can see that I'll have time in the coming years to indulge and I just can't wait.
