Let’s say I’m out how can get approached and non- verbally show that I’m single and interested without having to actually talk to him first?

For context: I’ve approached men first in the past, I’ve confessed my feelings first. But as women I want to feel what it’s like to be approached (not creepily obviously) but for them to actually make a move on me. I’m not gonna lie, it makes me feel less attractive (just a little) when men don’t approach me first. I’ve always wondered why some of my friends don’t have a hard time getting attention why I on the other hand need extra effort aka I have to do the approaching. I don’t know I mean it would be nice. But what can I do differently? What can I improve? Thank you just any solid advice.
