You got sucked in by the joke. “Transmaxxing” is not a real thing. It is a fictitious concept that certain social media spammers (originally on 4Chan) have fun with to get in the heads of the Incel community. (E.g. QAA Podcast Episode 239 “Transmaxxing”) There are no groups of Transmaxxers taking estrogen to try to enter women’s spaces and be accepted by them so that they can get laid. If you knew anything about HRT you would know that one of the major side effects of HRT is to make it far more difficult to perform sexually. It would be counterproductive. The whole thing is an inside joke, as fictitious as the idea that the Earth is flat. Trans people are under enough pressure from those spreading lies in other forums without adding yet another layer of fear to the bigotry. Be careful about what you share.
