Being a rationale person, I always try to figure out the why, even for crossdressing.
I would say that for me it is a mix of genetic and experience in my childhood.
Genetic, because as a little kid my brother used to dressed up as girl (me not at all).
Experience because:
As a kid:
- I used to play boys' games (football, video games (at this time it was more a boys' thing, biking) and girls' games (remember playing Barbie with my female cousin)
- I used to watch boys and girls' Tv cartoons with my sister.
As a teenager, once I saw a woman walking in heels in a movie, it must have triggered something in me and have developed some king of fetish for heels. But I do not really saw it as a kink thing, as ReineD said we engage in a lot of things. For me it is like why a football team became my favorite one. For me it was the emotion I felt during a particular game at a particular moment when I was young. This moment of the game is still in my head tweenty years ago.
My relation with my mom, with strong emotional bond but distant at the same time. We really look up to each other.
I have developed a strong curiosity for everything (it must be also a mix of genetic and experience) and never be afraid of crossing bondaries if i think they is no rationale reason for these bondaries.
Finally, with all that, it is almost logical if I became a crossdresser.
