This is something I have been wanting to discuss here. Its a very interesting phenomenon, I have noticed this as well. Tbh I feel its good in way, nobody deserves ideological bullying that gay men, lesbians and to some extent straight men are subjected to. Straight women just get called TERF for other reasons, not for this. Also, straight women are more picky in general, I've read that a sizeable amount of straight women refuse to date bi men as well. Now, consider this since straight women won't date the lesbian who thinks she's a straight man, this further shrinks the dating pool of "lesbian to straight male'' FTMs and tbh this is really sad. Young gay women need to carefully take their decisions, besides all the misery that lies within the genderist world there is also tons of loneliness. I have read some accounts of lesbians on reddit/twitter who transitioned to FTMs that their "sexuality changed" upon transitioned as in they eventually developed an attraction to males/penis. Not sure if "sexuality changes upon transition" or not, but I do think that this might be some kind of strategy to up their dating game, men on the other hand will at least have sex with them if not relationships, in some cases lesbians partner with such women but that is rare. Life as a transitioned lesbian FTM is hella lonely
