So here it is. You like this girl, you hold her to a high standard, and the pressure of performing good, and the nervousness of not performing good, hindered your fucking ability to perform good.
GAME PLAN TIME
1. Go watch some youtube videos, or shit on porn sites on how to make girls squirt, orgasm etc.
2. Go fuck some girls you don't about and it's mutual, do all this fun freaky shit let loos and enjoy and handle that shit like a fuckin boss, and get your fuckin nuts back, and confidence!
3. Go meet back up with this fitness (40 hours work week in the gym holy shit!) girl you like, because her fucking libido from being in the gym that much is through the fucking roof.
4. Notice how I'm saying ''Fucking so much''
5. Go make this girl feel so amazing she squirts, orgasms, and has a brief walk with god in heaven, before she cums back to earth, and regain your throne.
Best of luck man!
Actually if you took time to read what I wrote you would have seen that I was severely intoxicated and this led to whiskey dick. I didn't feel pressure to perform, I was literally so drunk I only remember bits and pieces of us hooking up lol.
