Flirting starts with not being attached to any outcome. You want to go into this with the mindset of having fun meeting someone new and interesting in the real world. And if it goes somewhere, great. If it doesn't, don't get discouraged. Instead, think of it as having had the opportunity to practice a new dating skill.
My sister and I love to head down memory lane, and we even try to drive by our childhood home every time we visit Cincinnati, the town we grew up in. One favorite memory is the party we had where all the girls danced in front of posters of Davy Jones and Mickey Dolenz. Remember how gorgeous Davy Jones was?
If you met an attractive man at a party, you would be showing him your best side and flirting up a storm. Your online dating profile is no different. It's the first introduction a man has to you. You are literally marketing yourself to the male population online. For some women that sounds horrid but in real life we do it all the time.
