You can ask all you want. But trust me, you'll know what the girl likes by her reaction to your kisses. And every girl will react somewhat differently and like something a little different.
I like long kisses if there's time, but short kisses are good just to show affection. I was really surprised how much I enjoyed French kissing, it was a really lovely experience.
Long kisses will probably be better but it depends on the person. It will work out in the moment, making out is not as hard as it may seem. Just look up how to kiss and ull be fine
