I've identified my biggest issue is pushing an interaction further. I'm really good at building attraction, and getting a girl hooked in conversation, but I always pussy out of pushing an interaction further. I tend to see signals telling me to push ahead, but I can never get myself to push the interaction further than maybe some kissing.

What can I do to get myself to push the interaction further? I know it's got to do with my fear of rejection so if you've got stuff to help me get over that fear please share with me!
