If you aren't willing to go take the time to educate yourself on the topic (there are ample resources to do so) then it is not our responsibility to educate you about trans people. Trans people are a rarity, so they tend to have to field the same like 20 questions a million times over. They just want to live their fucking lives, not answer truly ignorant questions about their genitalia from people who didn't put in even an ounce of effort to understand.
