I Sexted With A Guy Who Lied About His Age

so i met a guy online who said at first he was 25, later when talking to him he said he was 22, he showed me his birth date in his ID and it said he will be 22 in around 3 months, i believed him and the sexted with him again, how ever the thought of doing it with someone who i know lied about his age makes me feel guilty, like ive committed a sin. am i a bad person for it?
