I can't see a transman having anywhere near the same effect. Complaining that gay men won't sleep with them, despite their vagina. They would just ignore it or laugh.
Because, realistically, what could that transman do? Dominate him, bully him, threaten him?
Most transmen are lesbians, anyway. So I don't suppose it comes up much. Although, using the same logic, they won't want to sleep with another lesbian, right? Because that invalidates their male identity.
It's all such a mindfuck.
