I have a big problem in my interaction with girls, especially girls I like. I am hopeless in flirting. I am a good conversationalist and have no problem at all making friends, getting to know people, making them feel comfortable etc. It's great, but when I want to flirt with a girl I can't seem to be anything but this mildly interesting, intellectual friendly guy. In other words, boring as fuck, instafriendzone

So, how can I bring out the spark? To make things clearer, if there already is sexual tension, or she starts flirting, I don't have much problem in keeping the mood going, but it's the transition from "I ate pizza/my prof sucks/mundane bullshit" to flirting that I can't seem to make a transition
