Hasn't everyone asked themselves this question in their lifetime? Let's start with the basics...Fresh breath (no onions or garlic before kissing please!), well moisturized lips (no chapped or rough lips, that's just asking for a bandage later) and on the flip side not too gooey (who wants to feel like they're kissing a jar of petroleum jelly???). Now speed and pressure are going to be something entirely up to the person you're kissing as well. You'll be able to tell if it's too much if they pull away or basically stop kissing you. Kissing can be fun, but only if the other person is enjoying it as well. And if you're unsure of whether the other person likes your kissing, just ask. People sometimes, are more than eager to tell you how they like to be kissed.
