Orgasm

Okay so I’m a virgin( have not orgasmed- I was close once before but chickened out) and last night my boyfriend was rubbing me down there, I was about to orgasm but I changed my mind and told him to stop. After,I felt that all of my body (even my head) were numb and I wanted to cry. All day today I’ve been feeling sad and crying(idk lol) and the thought of orgasming makes me feel panic and fear. What’s going on?
