Best position for a virgin?

I’m 19 and never had sex. Me and my bf have almost been dating for a year and a half and I am on the implant. We will still wear a condom but I am just wondering what is the best position for a virgin? I’m a girl and hear missionary is best, but also some say riding is good too bc you can go at ur own pace. Should I buy a dildo to practice? Idk. I know about foreplay, I have fingered myself before. No hate pls i am just looking for advice thank u :)
