Am I being a good boyfriend?

It's been 3 months since my girlfriend and I started dating. She's 15 I'm 17. I don't see anything wrong with our relationship. We haven't gotten into any fights or arguments yet. I sometimes spoil her by buying her a new shirt once in a while, paying for her meals and movie tickets, etc. I call her every night before I sleep so that she's the last person I hear before my day ends. But I sometimes get nervous with her whenever I try to kiss her. Instead of her lips, I usually go for her forehead or cheek. Am I being a good bf?
