I went to Korea and Japan for about a month each after graduating from High school (m19). After learning the respective languages at schools, I wanted to use what I learned to make some native friends. I never had a girl friend, but after living abroad I realized I usually enjoy talking to girls more than guys, so to shorten this paragraph, I basically hung out in areas I had an interest In and got numbers. Now that I'm back home I really want to keep my relationship strong with alot of these people. Because of the time zone difference most of my communication is through back and forth texting, which sucks. I came to the conclusion that I need to do some light flirting with some of these girls, just to keep the text conversation exciting. Although I went on a few "dates" I consider these girls more of friends as I didn't want to be a bastard who dates a few girls then goes back to his home country, esp bc I haven't had a real first (longterm) relationship yet. Any advice for some playful flirting I could employ?
