Want to try some new things with my boyfriend for sex to spice things up guys what would you want to try with your girlfriend to keep it interesting?

Guys what are somethings you would do or want to try with your girlfriend to keep things interesting for sex? like more teasing before or new things that you just haven't done with her yet and girls what are somethings you have done with your boyfriend to keep it interesting? usually me and my boyfriend stick to the basics but last time he wanted me on top and I haven't done that to much maybe twice now we tend to tease a lot to get in the mood or when we are in public we try to stick to very casual teasing or if we are in his car we will make out a lot first to get more in the mood but I want to try some more new things with me but seeing as I am shy I don't know how to go about it also I just don't know to much of this stuff so I don't know any new moves/positions that I could do I figured since he's been busy with his exams the past little while here that maybe after school I would just go and meet him by his car and surprise him or just try going to his house after school he showed some interest in new moves/positions the other week by having me on top and before that he took my legs up around his neck and shoulders so I thought maybe he might be looking to try new things with sex so any ideas on what I could do? I want to do this as soon as I can this week so the help would be appreciated I know he's probably been stressed with the exams so I was thinking it could be a good way of taking some stress off for a night.

Thanks.

I should also mention when I was on top I felt nervous like I would screw up any tips for when I`m on top that will help me feel a bit more comfortable? is there a certain way to do it when on top?

Sorry like I said I just don't often try new things with it but also don't want either of us to be bored
