Well this is something to work on then, because it is causing you distress (and likely distress to these 4 guys as well). Pay close attention to what you say to these males, as well as how you say it. Work hard to ensure that each of these individuals is in the friend zone, and knows it.

It might also be worth considering what this flirting behaviour rewards you, since it seems to be a pattern. Perhaps it is a self-confidence booster, or you like the attention? Just a thought.
