There is no ‘proper’ way to kiss.
What makes a good kiss is different for everyone. Some like fast, dry pecks. Whilst others like a longer wet kisses. Some like snogging or French kissing, where you and/or your partner use a bit of tongue to explore your kissing partner’s mouth. It’s normal to stress about whether they’ll be a good kisser. But a good kiss is more about the person you are kissing than it is about your kissing skills.
