I don’t really have advise for lgbt as I am straight so my experience may not necessarily be accurate for you. But I think it’s safe to say that the broad process on how to meet others for potential partner is universal regardless of gender. I admit I’m far from being Casanova, but people in bars or clubs who are interested send signals, like eye contact, smiling, inviting you to the dance floor, etc. It sets queue that you can approach them without looking creepy. But that’s not even foolproof because sometimes a person may only be looking for attention as he/she may have a partner all along.

Another avenue to meet people would be taking part in social clubs and interest groups. You would be sharing common interests so it would be easier to have conversations. Hobby groups and social clubs don’t usually involve alcohol so if you’re not into drinking then that’s a good way to meet people.
