Is it perversion though? Because one would think that the sex drive goes away from the chemical castration.

Let's take a closer look. The majority of trans are MtF, yet nearly all detrans were FtM. And if you take the red pill, I think that pretty much wraps it up. Women simply have it a lot better than men in general, biologically and socially. There's a reason they're always much happier, even in countries that treat them like shit. So the truth is that a lot of men are just sick and burned out and depressed from their burdens, and see the privileges and easy living that most women have handed to them.
