I am a trans man with a functioning penis, balls, and vagina. AMA!
My short bio: I was born female-assigned and I began transitioning to male at age 16. I had a mastectomy ("top surgery"), hysterectomy, and oophorectomy. For my bottom surgery I chose to have what's called a simple metoidioplasty with testicular implants. My clitoris, which has grown due to testosterone therapy, was released and I treat it as my penis. It's small (thin and 1-2 inches depending on arousal) but it's mine and I'm proud of it. I elected not to have a vaginectomy because it would mean a loss of vaginal orgasms. I pee from a hole just under my balls.
Other than this I'm your typical 24 year old guy. I had the last surgery just a few months ago. Before you start to feel bad for me because of my size, I ought to mention that I'm gay (attracted to men) and a bottom.
Edit: I'm out for tonight, hope to answer more tomorrow!
Edit: Thank you all for a fun and largely uplifting AMA experience. I found myself bored, made this post, and had no idea it'd get so much participation!
Answers to Common Questions
I pee through my urethra which is where it always was, right above my vaginal opening.
It's possible to receive vaginal penetration. To get an idea here's a photo of someone else with the same surgery. NSFW pic
My surgeries were all paid for by publicly funded health care in Canada. Some provinces in Canada cover some trans related surgeries. If I had paid out of pocket I'd have spent around $50,000 CAD total.
I'm soft/semi in the photos. I can get erect to a max of ~2 inches. I don't ejaculate. I do get wet.
I couldn't have stayed a girl. I don't care if women have an easier time dating guys. I'm a man first, and I needed to be true to myself so I transitioned.
I haven't had sex yet after my final surgery but I'll be sure to report back how it goes.
