What to do when with your girlfriend?

Hi all! I’m a 17 y/o guy who didn’t have a relationship yet. I’m not going to ask how I can fix this, but more ‘what to do when in a relationship’. Friend of mine are starting to get into dating more and getting girlfriends and such and girls are also starting to play a ‘bigger role’ in my life. I don’t consider myself as ‘boring’ but I also don’t consider myself as ‘not boring’: conversations die off relatively quickly sometimes, and because of parents I can’t go out that often. And this all got me thinking: when I get a relationship, what the heck am I gonna do with her when she’s coming over/ when we are going to hang out? Kiss/cuddle 24/7 will get boring after a while, going out or movienights everytime isn’t going to work and after a while you run out of things to do… Can you guys enlighten me and give me idea’s/tips/insight what you do? Thanks! F
