How to: ask for advice about relationship

Hi Marc
We've been on holiday here in France for a week now and I've just met this guy, Mikel. He's georgeous but I'm not sure how I feel about him. I need your advice.
I met him on the beach yesterday and he invited me to play tennis. Both of us were having a real laugh and them Arnau invited me to a coke with my friends.
I've been thinking about things a lot since then. I'll probably see him later , but I'm not sure what to do if he asks me out. He seems very different when he's wiht his friends. What do you reckon?
