I have recently turned 18 and I have found out I have a fear of being rejected ever since I have started to go clubbing. I have only been 3 times so far however each time I have tried/ had chances to 'pull' a girl only to be left frozen when I tell myself to make a move. I have had relationships with girls in the past but I never had to physically make the first move as the relationships just kind of came together if that makes sense. I also have managed to pull without making the first move at parties.
Basically, I have no knowledge in how to make the first move and I am scared of getting rejected.
Is there any advice or tips I can have?
