So I'm a decently outgoing person. Im not afraid of talking to anybody, and in conversation I can make people laugh. When I'm with a girl I'm interested in, I have no problem conversing, making her laugh, I'm kinda shit at flirting but I'll do what I can. But where do I go from there, how do I transition from a conversation, to hooking up? Are there signs that I should be picking up/giving? This question mostly pertains to a party environment, but I'm curious how to do this anywhere.
