I don’t think experience matters a whole lot because everybody goes into a new relationship and technically has “no experience” with that new person. I think the fact that you are already sincere and respectful is excellent. I also think making sure you have common interests is important. When relationships are new, both people want to spend time together. It’s easy to do things together because you’re eager to see that person. In my experience, people drift apart when they don’t have enough in common. So my advice is to ensure common interests and always place communication and respect at the top of your priority list. It sounds to me like you’re already on the right track.
