I posted too early, sorry
It's like any other sexual preference - you just know, usually from a young age. For me I had some idea when I was about 12, based mostly on things that used to excite me with regards to girls. But I knew for sure I was a dom when I was 15, after my girlfriend and I tried something together and it was like ... this door in my head opened up, and I was filled with sunlight, and I thought, "Wow, this is it. This is what I've been looking for." It was a quasi-religious experience, really. There was no turning back from there. Once you learn the truth about yourself you can't ignore it.
Well, I always did stuff with rope since I was 14~15, so I guess I did know as soon as I started caring about such things.
I'd rather be dom'd than be a dom myself. It's weird.
This is coming from someone who's fantasized about being raped. I shit you not.
That one's a fun fantasy...as long as it remains such. I know the reality would be horrible.
The scenario of 'being forced against your will/raped and then driven to the point where you're in ecstasy and begging for more' is one of my favorites.
Stay out of my head
Well yeah, Buck Angel is for all intents and purposes a man with a vagina, while a dick girl is a girl with something that you're not entirely unfamiliar with.
... is it bad that I already knew who Buck Angel was without searching for it?
Meh, spend enough time on /d/ and you know it rather quickly. That pic comes up a lot.
So wait... there's actually people who'd want a me over a real girl?
?
You didn't know that? TG has quite a following. The problem is that they tend to focus on the parts I assume you hate, rather than your womanhood. Or so I've heard

Further, you are a real girl
Ammy: natal vs ts girl is still a distinction :V I wouldn't have all the parts and my hole would be... shall we say... a lot different on the inside than a normal vagoo.
I still say you are a real girl
And Jan...TSO is a girl...
Jan...do you get it? I'm not sure...
