Recently my friend told me that her friend finds me cute and dreamt of making out with me last night. She told me her friend is interested in hooking up with me BUT I've NEVER had a hookup before. [ I'm 23 M ]

I got out of a 3 year long relationship, 4 months ago and I think it'll be nice idea to flirt with other people.

How should I proceed?

Extra Details: We're a group or 3 girls and 3 guys and will be staying in an hotel room tonight after the night club. I think we'll have sufficient space to talk to each other.
