<human>: Can you summarize the given text in a few sentences?

I'm not a weird girl, or particularly unappealing in any way. In fact I'm pretty confident in my looks and personality, it just so happens that I've never gone far enough with a guy to get into a real relationship.

Today my SO asked me to be his real girlfriend after about a month of kind of "being together." By "being together" I mean we've held hands, kissed, and had sex. But now it's official.

I just want this to be a completely smooth relationship with no troubles, especially because I want my remaining months of senior school year and hopefully summer to be happy and lovely. And because I've never been in a relationship, I wanted to ask you guys if there is anything I should definitely DO or NOT DO in order to make sure this is something that I will cherish and not stress/cry over.

I know it sounds super lame but I really like this guy and I just want to make sure I'm not the inexperienced girl that ruins the relationship through some stupid mistake.
<bot>: ! I'm entering my first relationship ever. What are some do's and don'ts for me to know in order to not fuck this up due to inexperience and naive choices?
