>>81513981 (OP)Before you get going be honest about your circumstances whatever they are:
Privacy: do you have anywhere you can actually be alone with someone? Can you afford a decent restaurant, or at least a couple hours at a nice cafe? If there's no bedroom for you to go back to, then it's not fair to expect that of them.
Presentation: No matter your looks a little personal grooming goes a long way. You don't need damn tux, but the cleanest most flattering clothes you have, yes. Start there.
Presumptions: What are you actually trying to do here? What do you want? Just wanna fuck? Looking for the one? Something in between like most people? Figure it out, and say that early.
Major first step is simply looking in a context where that's appropriate or normal. I.E. Bars, clubs, dating apps, leisure activities where the bare minimum of some spare time is expected. (don't bother people at work)
Next step is not wasting your time or theirs, don't pursue people who say explicitly they're not interested. If someone actually acts like they're picking up what you're putting down, that's when you start wasting your own time without obligation to them. The most direct approach that respects everyone's time and dignity most is to simply offer your own number (or whatever way to contact you), put the ball in their court, and walk away. If they liked what they saw, you'll hear back. Either way you find out without imposing.
Last, have fun dummy. Try to have a good time, see how they have a good time. Take an interest in them and their hobbies. If you don't know how to do anything you like together it's not worth it.
