Confused about sex

Molly • Add my ig ☝🏻

I’m with a girl rn and we’re only 15 but we want to try new things (sex) we’ve already done stuff, we’ve gone down on eachother, and that’s the furthest but she seems to think having sex is scissoring and we haven’t done that, so have we had sex or not? We’ve gone down on eachother but not gone any further, someone please help im so confused
