Taking it to the next level

So my boyfriend wants to finger me, he also wants to do it at school and there really isn't any other place to do it, but I don't know if I'm ready for him to do that yet. I'm still a virgin and he knows that and he's okay with waiting if I want to. We've done other things but he hasn't really been in my pants besides grabbing my butt. What do you girls suggest I should do?
