I can't speak to the heritability of crossdressing. But I have this...
Around age 10 maybe, my mother, sister and I returned early from a cinema visit to see a woman coming down the stairs
Stay put, us kids were ordered as my mother legged it up the stairs after my hastily retreating father.
Nothing was ever said.
Then as a teen I found, under a loose floorboard a bag of lingerie that had been, ahem, 'enjoyed'.
Suffice to say I wasn't bringing that one up.
So imagine my surprise to find myself here at age 47?
I cut all ties with my family 12 years ago but you better believe in the 18 months since I started dressing I've chuckled at the thought of asking my father out for a pint, dressed, and saying 'well...?!'
Heh
