Men who transition later in life are usually autogynephiles. (AGP). Lots of these men have an extremely toxic and sexist view of women already, basically seeing women as sex objects. They are heterosexual and possibly porn obsessed. Somehow their sexual fetish for objectifying women migrates over to a sexual fetish of seeing themselves as the sex objet woman. This is why these people end up being the really creepy ones. They don't just want to be a woman, they get a sexual thrill by forcing other people to see them dressed up as a woman. They like to go on Reddit and talk about how they get erections by putting on female clothing then claiming to know women also get sexually aroused by putting on a dress.

The men and boys who transition early are usually the HSTS variety. (HomoSexualTransSexual). This seems to have a wider range of reasons. Some of them project a vibe of failed men because they are effeminate or just because they fail the gender role of "man" by not being attracted to women. This gender role failure is the reason this group fits into extremist religious right ideologies. Pat Robertson and Ayatollah Khameneh have weird alignment that "gay bad but trans ok" because being gay breaks gender but being trans fits into the culture.
