Recently met a boy and he was extremly sweet at first but a couple days ago he keept getting pushy about sex and wanting explicit pics of me (I repeatedly told him no because I feel extremely self conscious) and he told me not too be too uptigh and just allow him to have intercourse with him. He then sent me multiple explicit pics of his genita aera, which ultimately let me to blocking him and cutting contact. However, I still feel like I acted wrong and ruined the start of a relationship (I have never been in one). Was I too uptight?
