Virginity

I am 16 and lost my virginity a couple days ago. It’s been bothering me so much because I was under the influence of alcohol and it was with a friend of mine that I would never consider someone I see myself with or would do anything with but for some reason it happened. Ive been worried he would tell people and I don’t want it to ruin our friendship but I’m not sure what to do. I just wish it never happened. This isn’t how I imagined my first time would leave me feeling. I feel disgusting. I just really need some advice right now because I feel like I can’t tell anyone except for my best friend and her advice isn’t helpful to me at the moment.
