The “hrt will make you boy crazy” is just some genderplay kink, it’s harmless and fun for ppl who are into that kind of fetish
there are dozens of girls in my notes telling me how scared the idea of suddenly liking men made them. it's such a pervasive idea that im constantly seeing freshly out girls terrified and asking for advice because they desperately don't want it to happen.
I've never once seen it even be used in a kink context come to think of it, it's always some poor scared trans lesbian desperate for it not to be true and a bunch of people saying oh don't worry about it if it happens it happens men are actually great tehe.
If you need to hear this, you can be a trans woman and a lesbian, you are allowed to like women and it doesn't make you a predator or any less trans. i love you <3
