Yeah, in a way. I'm hetero but I've lived in isolation (homeschooling) since puberty began and was put on SSRI's at an early age to combat the misery that it causes. I, too, have always held a traditional view of masculinity and I was deeply ashamed of my psychiatric history which really screwed my life over as soon as I entered into adulthood and understood what it meant to have one especially considering that it could've been dealt with in another way (if only my parents weren't utter fools.) I have absolutely no experience whatsoever with dating and I wanted to have a clear head before I delved into it but that day, when it had finally arrived, came too late to save me. I enjoyed weightlifting when I first discovered it in my early 20's but my depression always killed my motivation so it's been a continuous stop-go-stop-go activity. If I never was put on medication, I doubt I would've been offing myself so early in life (<30).
Of course, I have some physical traits that I was insecure about. Nothing that caused me to lose any sleep but has been the source of annoyance and frustration.
My weak jawline has always been my #1 insecurity, so-much-so that I am compelled to grow my facial hair out to conceal it although my patchy beard doesn't do a terribly good job. In a distant second, I am myopic so glasses are a must and I've always hated having to wear glasses. I am also well-below average height for my ethnicity but that also comes with advantages so I don't consider it a flaw outside of passive social dominance.
With that being said, I also had things that reaffirm my masculinity such as being stocky and barrel-chested so physically speaking it's not all bad. I've also had nothing but masculine hobbies and what I study in school is masculine as well. It's the mental stuff like my regrets coupled my parent's copious failures that had been killing me slowly over the years.
PS: I fucking HATE being sexually mutilated (i.e. circumcised)
