Since I was young, I took a special interest in martial arts. At one point I held a 1st degree black belt in TKD as well as Hapkido, and was a self-defense instructor. However, due to a few injuries I sustained, I had to drop the TKD (and other hard styles I learned) and went into the softer arts, and focused more on the Hapkido I learned as a child.
I won't get into the list of things I tried, but I wound up settling on Wing Chun and Tai Chi as they are "gimp-friendly" and thus do not focus a lot on being overly-strong or in "great shape" to practice, as well as (if you find the right instructor) having some decent self-defense techniques that minimize the risk of being harmed yourself by breaking your wrist by punching wrong. They integrated well into my own personal style (that I keep to myself.) While not practical at the pace the forms are practiced, I like the "art" side of Tai Chi as it is very calming and makes me feel pretty hahahaha.
I never really fancied myself as a "TKD Person" or a "Kung-Fu Guy/Gal", instead preferring the term "martial artist" because I think styles are too confining. Learn everything, keep what works, discard the rest. Kind of like Bruce Lee...just not as good. Or fast. Or strong. Or good-looking.
Martial arts has helped me get out of trouble on more than one occaision, as well as kept me in shape and is a good stress release...and by "get out of trouble" I mean not fighting off people par se, but rather, how to remain confident, collected, and aware of my surroundings. (The best defense is not to be there. Violence is a last resort: escalation is something to be aware of.)
I am really glad I trained over the years, especially now I am going through the transition process. I feel 1,000% safer knowing I can at least hold my own against "90%" of the people out there. Call me biased, but I encourage everyone (especially MTFs) to get some basic knowledge of self-defense in case they are left with no other option. Also, if you got anger issues (like me) it is a good place to vent.
I recently broke it to my Wing Chun instructor about my transition, and I told him if it would hurt his business I could leave or he could train me in private/under the radar. He told me that if people had a problem with it, THEY could leave. So, I think I found a place I can train more full-time now.
