Dating and insecurities

So I've only ever been on like 1 date in my life. I'm in college. I have never even kissed anyone. I feel very uncomfortable with touch and guys in general... But I would like to get myself out there and just experience dating. There's this guy I've been talking to through an online dating app and honestly I think he's really cute. He wants to go on a date this week but the idea of that stresses me out unlike anything else. Usually I end up ghosting guys I talk to, but that's a bad habit. I am worried by meeting in person, I'll be a disappointment because of my acne or because I feel fat rn. I also don't really know how to not be boring around new people. I don't know what to do. I don't want my insecurities to hold me back, but I don't know how to feel better about myself to the point where I'd be comfortable on a date.
