I never had anything related to genital dysphoria. Perhaps it's because of my fatalistic attitude about life. Sure, I wished I didn't have the dangly bits, but now what? You work with what you got. Up to an including wild monkey sex. The dangly bits and I have had some great times together with company over. As you can imagine, that had absolutely nothing with my tipping point
Mine came when my life once again turned into a total disaster. Oh, it happened a few times before, but this time it could not have been worse with me actually living through it. I lost my job at the peak of my career, VP of Engineering. I did manage to land an engineering gig. At least that is what the military industrial complex said it was. IMO, I was a glorified admin, able to do the job with most of my brain tied behind my back. Not exactly what a super hero engineer is used to. Add in it was 350 miles from home, the height of the housing crash/depression, a semi invalid depressed wife, a long distance marriage, and complete isolation and culture shock as I moved from 5 miles to mid town Manhattan, to rural West Virginia.
In other words I had to much quality time alone with myself and my thoughts. No more 3D's, as I came to call them. Diversions, Distractions, and Denial. Nope, every aspect of my life that relied upon "to get by", was gone. Given the choice between eating the barrel of my favorite gun or doing something about how I was NOT handling being trans.
