Want sex but so anxious and awkward around guys

So I’m 18 I’m not a virgin but recently I’ve been horney all the time and I’m always in the mood to do it but I don’t want to step up and start taking to a new guy because I’m awkward with it because I don’t have much experience. I am bad bad at sucking d I can’t ride d that good (granted I’ve only had sex twice) so I’m scared to get with someone and them not like it. Plus I don’t know how to be in a relationship because I’m not a clingy person and I get anxiety when people show love towards me. What do it do and how can I get over this. I was thinking about maybe doing a tinder hook up or something to try and get experience first. Before I get a fuck buddy or something.
