I'm sorry, is the complete question "what was your tipping point for starting transition?"
I mean everybody seems to be assuming that THAT IS the question. But there could be several other "tipping points" in life, in my own case:
--For realizing I hated having a guy's body: very early in life. Somehow i wasn't keen on my genitals, for some reason I just couldn't figure out
--For starting crossdressing very frequently: as a teenager when I saw my older sister wearing a tube top shamessly on the beach, when she had just started puberty and had already developed a nice pair of breasts, having tons of guys drooling for her, at that point I totally hated being a guy, I wanted to be like her and I felt so miserable
--For starting bodybuilding, my biggest stupidest mistake in life BTW. IDK really if it was the beatings in elementary, being threatened with a knife by an a-hole in high school, being bullied on a daily basis at the same period, being friendless and rejected as a"guy", wanting to "fit in" and being admired by my folks, siblings, classmates as opposed to ridiculed...
--For leaving my parents' home abruptly, with no income or place to go: gosh it was a myriad of things, mainly confusion about my gender issues while I had become a huge "guy" physically but my mother suspected I was secretly crossdressing, and didn't like women, just pretended I did, etc I was a total mess IDK why I didn't terminate myself at that point
--For moving away from my whole family to California, with a couple of guy friends, supposedly to start a rock band or enroll in the Musicians Institute: again, a myriad of things set off that abrupt decision. I just needed to go away somewhere else
--For moving back to my original city: again too many confusing things were happening to me, as well as a bit of drug and alcohol abuse and even smoking while living in California, because of huge work-related and survival stress and hating living as a "guy", on a daily basis
--For moving back to live with my parents: basically, feeling extremely lonely, vulnerable, suicidal and having been living in dumps filled with mice, rats, roaches, spiders --although I really don't hate them spiders much as the others lol, I rather fear the poisonous ones, but I do like how they look-- for years
--For starting HRT (not really transition, just full-fledged HRT): primarily, it was the fact that those advertised methods including herbs and similar stuff, supposedly aimed at developing breasts and feminizing the body, were a waste of time and money for me, but I was scared to death of HRT's supposedly terrible side effects.
--For realizing I am a transgender-transsexual person: I really don't know! I was already on HRT for more than a year and I still thought at that time that I was a crossdresser, I actually called myself a "t-girl" at that time, but didn't even know what that meant! I was in awe of actual transsexual women, feeling like they were some sort an impossible ideal for me to become. Like some sort of fantastic being with special traits and capabilities that I just didn't have and could never develop. I guess when I started getting on Web sites such as this one, is when I started "discovering myself", for the first time, and realized that being a transsexual is not about passing 100% as a cis female, or being an incredibly brave and strong-willed super-special human being. It is rather about KNOWING that one is (in my case) a woman inside, regardless of how accurate the body may be to match that feeling, as a true physical representation of that inner-being, specially to conform to our currently absurd social standards and stereotypes.
--For finally acknowledging I am a transgender/transsexual and REALLY ACTING UPON IT: When I read an AWESOME article from a successful transsexual woman, about orchi, how it did wonders for her before she was ready for SRS financially, regarding getting rid FOR GOOD of the poisoning agents that produced testosterone. I had always hated those things since I was a little "boy" anyways. I was about to terminate myself at that point, then I read that article, and a couple of months later, I finally had my orchi and t-shave. THAT DAY I was 100% sure I was no longer a "guy" physically, so my mind started to match my body AT LAST
--For starting seeing a psychologist and later, only briefly, a gender therapist: too much emotional baggage. Too much pressure/many questions from my folks about why I had no friends, no "girlfriend", failed at all jobs I got hired at, was locked in my room sleeping all day and doing all my stuff all night, to avoid my parents...
--For "coming out" to my parents: One day, it was just one day I just exploded and told them, crying, that the real reason I accepted going to the psychiatrist, was not "sleeping and social problems", but it was that I had hated being a guy my whole life, I had Gender Dysphoria or Harry Benjamin syndrome, confirmed by the doctor, and that was the root and cause of everything, all my personality and social problems
--For starting presenting as female, after more than five years on HRT, and almost as many after orchi and t-shave: even though I was scared as hell about not passing, being rejected, etc., I totally hated the idea of presenting as a so called "androgynous guy" so much, that I took a chance for the first time. My BF's support and encouragement was a huge help for me on finally doing this. I don't think I would ever have started presenting without him.
And there are so many other tipping points I haven't mentioned. But as usual, I already wrote a HUGE essay one more time which probably very few people will feel like reading in its entirety, if any. So I apologize in advance for taking up so much space in this thread. Maybe someone could find it an interesting story/read though. It's real stuff, commonplace in many MTF's lives actually, so it could be an eye-opener for the ones about to start transitioning. It's a roller-coaster, but it's worth the trouble, for finally becoming one's true self and slowly becoming a happier, more likable person and even getting some invaluable peace of mind.
