Whenever I try to hit on a girl , I always end up talking to them like I'm just a friend. So its hard to transition to anything more. Even when a girl is obviously interested, it seems like the big thing to change from us talking to the kiss. My style is pretty layed back, relaxed. What are some fluid and subtle things I can do to make my approaches more flirty

What's the best way to fix this?

Thanks :)
