I'm kind of like that now and I haven't yet started HRT. I also never projected as tough or alpha male, but I do own a gun that belonged to my grandfather. I've never fired it, though. But yeah, I'm just as cautious. When I go anywhere at night — even to the supermarket — I'm constantly surveying my surroundings. I don't exactly look or walk like someone capable of defending themselves, and I have no muscle. I'm highly considering firearm training and getting a CHL, but before that I'll just carry some seriously debilitating pepper spray. If HRT makes me feel even more vulnerable then either of those things just might be necessary for my peace of mind.
