Open Question: How do language patterns manifest themselves in culturally specific thought processes, such as orientation to?

You know, online dating is a waste of time if you date keep fixated on just "one person a time". Some take way too long to have a first meet, only to find out there's no chemistry. Some never intend to meet, just fishing for compliments. And some are just plain players or cheaters. But if you talk to/date multiple people: how not to appear like a player yourself? I mean I'm a sincere guy and I don't want to play with others' feelings or waste their time either. How should I do it? I put this in LGBT because I'm a gay guy (in a small town) so I hope you can understand the situation more. Thanks!
