Every girl is different. Some even like biting (some even harder than others!)
Though in the beginning of a relationship, sometimes riskier things are best approached once you're a bit more comfortable with one another.
The trick is to try everything and watch (and listen) to how she reacts to it. You could also ask her what she likes too.
Some things are pretty universal, like having a sensitive neck and surrounding area. But you'd be surprised at the range in which a girl's breasts can be sensitive. For example, I find my nipples aren't that sensitive to being licked until my boyfriend gets a bit more "intense" about it, and I actually find the area right underneath my nipple more sensitive. And I like a little nibbling. Not all girls could say the same.
Feel it out and as things progress you'll become more comfortable to inquire about things and try different things. Just do your best for now, and remember that google is your friend.
I like when a guy comes from behind me and kisses me on the neck and presses against me, I like soft kisses on the cheek (they're really sweet and they don't scream "i wanna get in your pants), I like a guy to softly touch my face, because it's a sign of passion :) but everyone has different prefrences lol
