Firstly, the transgender child has already exhibited (or hidden) some gender variance for several years before they arrive at puberty (I wasn't older than 4 when scolded for wearing my mother's shoes). But when they hit puberty a dilemma occurs: the object of the sexual attraction is also someone whose gender they identify with either fully or partly. This contradiction affects the imprinting of the sexual identity but it is not well described as target location error but rather as a pull in two separate directions which leaves the gynephilic adolescent facing two distinct paths. I was keenly aware of this problem but wanted to be normal so I suppressed the dysphoric feelings as hard as I could. I wasn't attracted to my own image as a woman but rather to the idea of being a desirable woman as well as being with one. That juxtaposition fused to my gender core and I was left with a riddle to solve: choose one or the other but not both.
The sexuality is in a sense left in a kind of limbo where one is neither complete man or woman. You are like a blossoming woman only with male equipment and nothing feels quite right. You also learn you cannot please a woman properly without imagining yourself as one during intercourse which brought me much frustration and shame. Some gynephilics are virtually asexual before transition and the process sometimes sees them reverse orientation and solve their problem. They can now be the object of affection of a man and become that desirable woman that they fantasized being. This is a best case scenario.
Today gynephilics who don't reverse orientation post transition can find love by pairing with bisexual women who accept them as they are. The years of hiding and suppression we went through are avoided. We should remember that there is no such thing as perfectly normal sexuality as evidenced by the Kinsey studies of the late 1940's. There is instead a scale which means that transgender people whose sexual identity has been impacted by dysphoria have a greater chance at happiness than my generation did. They can fully accept themselves first and then find the right partner if that is what they desire.
We also note that this arousal greatly dissipates with age leaving the original transgender identity completely intact if not stronger.
But even if my fascination with the mechanisms that created me continues, something has changed. My primary concern is more how I feel. We should all ask ourselves: Am I happy on my current path? If so then we should stay on it.
