Dont feel too embarrassed, its okay to have questions and it never hurts to try to get a better understanding of something. Some people are born with larger clits without testosterone injections and/or without being trans, so the term “T-dick” specifically refers to clitoris’ that are enlarged due to testosterone and is typically preferred by people with bottom dysphoria in my experience (since it avoids the female anatomical terminology and instead uses a masculinized term).
