The name for a discredited theory that transgender women are merely sexual perverts. The idea is that trans women get aroused by the thought of being women, and because of that arousal go on to present as women.It is not possible because of gender dysphoria , the idea that it is uncomfortable to present for an extended period of time as the other gender. As soon as such a person ceased to be aroused, he would become very uncomfortable indeed.That it is incredible, and divorced from reality, does not stop transphobes from using it to attack trans women and feel good about themselves excluding us.
