i'm not even sure that this is a case of transphobia. if i had to take a guess i'd assume that this insult to feminists everywhere saw the word "nudes" and immediately assumed

1. OP was a woman, who
2. was sending naked pictures of herself to a man, who
3. did not know her in person and had coerced her into doing so

i'd bet money that the "feminist" described here is the sort of person who views all sex workers as victims of the patriarchy and refuses to believe them -- or, better yet, tells them they're confused -- if they say they actually enjoy doing it
