How do I put myself out there

I’m kinda new to Reddit, I usually come for the memes but found this Reddit so thought it wouldn’t hurt to ask for some advice. I’m 22 years old and I’ve never had a girlfriend before. I was pretty well like in high school by my piers but I never really got the sense anybody liked me enough to date me. It could be because I’m really shy and afraid of saying the wrong things or getting rejected. After high school it never really bothered me as I was trying to find a living for myself but now that I have a stable job and income the thought of finding a relationship came back and was amplified by all my closest friends now being in a relationship. Don’t get me wrong I’m super happy for them and not jealous, but instead I feel like I’m the one with a problem. It feels like every one around me is in some kind of relationship whether it be co workers or other family members and I feel like Im not good enough or falling behind. I just feel like I don’t put myself out there in the right places like my friend joe found his girlfriend online and those two hit it off cause there were into the same thing, but I feel like I’m not as bold as him. And I feel like nobody looks at me with any interest but I could be imagining things. I don’t know what to expect but any advice would be helpful
