Alright so this is my main problem, Im not sure if its a confidence issue or lack of experience but Im curious as to your own personal solutions to this issue.

I see a cute girl and my brain immediately thinks "yeah she's a babe but her boyfriend is around here somewhere ready to step in and shut you down"

Its seriously pissing me off. I mean, do I just man up and talk to her? I feel like Im a fairly attractive dude. What would you guys do to correct this?
