I'm not talking about hardwired thinking, but rather that life is experienced differently due to GID. Here's an example of what I mean. I know there are exceptions (which is why I use the word 'Many'), but it demonstrates how the experience is going to be different. This is based on what *I* have read and observed of FTMs and GGs. In other words, it may be wrong, but this is where I'm coming from.
Breast growthGG: Many see this as a rite of passage into woman.
FTM: Faces this with horror and sees this as a time of extreme torture because they are forced to experience changes to a body they do not want.
Wearing DressesGG: Many seem to have no problem with this.
FTM: Sees this as something that utterly disgusts them and causes them misery. Unless forced, they will generally avoid dressing in feminine clothing.
Giving birthGG: Many see this as a celebration of their womanhood and look forward to it.
FTM: This is something very few FTMs would ever consider doing.
Perhaps whether attention from men is perceived as unwanted and intimidating varies just as much with FTMs as it does for GGs. In other words, some may find being hit on annoying, unwanted, or even intimidating (maybe the person just isn't ready for it yet) if those people are not interested in men, and it seems many FTMs are straight.
Anyhow, back to topic of the OP. First of all, I don't mean this to sound arrogant or like I'm bragging or anything, so I tried to word it so it didn't come across that way. If it still does, that was not my intention, nor how I feel. I have been thinking about this and I realized I actually *do* experience at least some guilt. I think this is perhaps one reason why I pursued trying to find out if I was IS. At least it would provide an explanation why somebody who started transitioning at nearly 30 and has had absolutely no surgery, and is not IS passes without problem regardless of the type of people I'm around. I've heard that teenage girls tend to be the best at spotting a TS, since they are constantly comparing themselves to other women and they are much more likely to verbalize any suspicions they may have. Well, guess what most of the cast in the musical I'm in consists of? That's right, plenty of teenage girls, and they have given no indication that they are perceiving me different than any other women. Also, I have had ZERO problems with anybody since going fulltime.
I know I have been read right at the beginning, so I certainly won't say I have always passed perfectly. It's certainly possible that somebody may have read me as TS, but it sure seems like I'm having no problems. So, then I read about others who are getting harassed and having plenty of problems (even hearing about problems in the area I live/work in). Even a friend *I* thought passed really well told me she's been read at least a couple of times, so it's not like everybody is accepting or nobody ever says anything. So when I hear about people being harassed or having problems with passing and my experience has been so much different, I guess I look for excuses (for instance, looking into being IS) so that I don't have to worry about others feeling jealous because then I can just say "I have this particular experience because of such and such, so you don't need to feel jealous." To me, saying something like "I guess I was just lucky" just sounds like you are mocking the person. This worry about other people's less positive experiences makes me feel bad that they can't have the same experience I do and that causes me to experience at least *some* guilt.
