Coming out to friends and family this weekend

Ok so first off thanks to everyone on this subreddit, while I've been in the closet you've helped reassure me of my identity and I can't thank you enough for it. I met a guy on tinder 3 weeks ago and went on a date with him. I'm 20 and I'd never dated or even kissed a guy before so this was big for me but long story short he's amazing and we both like each other a lot. We've been seeing each other for about 3 weeks now. Only about 5 of my friends now I'm gay but after meeting this guy I'm ready to come out to everyone else. I'm planning to tell my parents and brother in two days during supper. Also there's a house party on the weekend and all my usual friends are going, some of whom know I'm gay and dating this guy. We were planning to show up together and come out to all my friends and essentially everyone I know. Do you guys think this is a smart way to do it? I've been holding it off so long and I know I'm ready I just don't know when or how to go about it. Thanks for reading this far :).
