I'm not very drunk and this just happened right now.

I was really hard but after putting on the condom my rifle just went dead. I still fingered the girl and now she went to sleep but it's still super embarrassing.

Do you know what happened and how can I prevent it?

Maybe it was bad timing but I jacked off like 12 hours before, this girl gave me some blue balls yesterday and didn't knew I was getting lucky today with her.
