Taking his Virginity

Okay I'm 16. I'm a junior and my boyfriend, 18, is a senior. He's a virgin. I've had sex before but all I've had is one night stands...or twenty or thirty minute back seat screwing sessions. This is different. This is actually emotional and I'm scared that his first time won't be amazing because I've never had that amazing making love experience. Shit, I haven't even had an orgasm. I'm just scared that he'll expect something amazing and idk how to make it so. How do I make it special?
