First time hookup advice

Hello,I have been mulling over going to meet guys for a while now, just download grindr last week I get tons of messages and people interested but I never pulled the trigger. Then I started talking to this one guy and I am very interested and I think I should do it but my inexperience is nagging me in the back of my head. I know the fact that if I never do it I will always be inexperienced so I am pushing myself to do it and break out of my comfort zone for a night. Any advice on approaching these feelings and how to prepare for a hookup? I am full of butterflies.
