Managing your end game

[Rookie]

Hi. I've been actively working on myself in general for the past year and have made significant results. In the past two weeks i've been hitting the clubs and bars hard going out 4 times a week. And have many girls very into me, touching me, flirting and getting very much close to me. Basically ready to go home with me. I'm proven to myself that I have great game and fundamentals however when it comes to pulling or taking that final step I freeze. I refrained from posting this here originally as I thought my problem was minor and easy to fix but I've lost around 8 lays and I really and getting frustrated with this.
Is there any mindset advice or hard and fast rules I can employ that will help me out here?

Many Thanks
Rookie

After doing some thinking I've realized that the position I'm in is a lot like being on a 7 meter high diving board. There is nothing mentally I can do to jump off because deep down my instincts here are stopping me from doing it. The only way is to trick myself and "fall" of the diving board. I know it's immature or childish but this video describes what i'm talking about perfectly, (the end of the video is the scene i'm talking about): https://www.youtube.com/watch?v=spvmRvbIlQo
So is there anyway i can trick myself into "falling" with girls at the end game?
