Hi, I always love hanging out with girls but for some reason ive become really awkward. I never know how to go from hanging around in a group to becoming close to the girl and actually hooking up. In about 2 weeks me and 3 friends are going to an open house and drinking and smoking with these 3 girls, but i am worrying about a situation that has happened many times and i am scared will happen again. We all sort of sit down and get in our spots and were smoking/drinking but i never know how to make the transition to hooking up and it gets awkward and i get nothing that night. How can i make the transition? What do i say or talk about? Also what do i say when i first see this girl? ive never met her, were literally just hanging out to hook up so what can i say to her and what can i do?

Thanks in advance!
