Im a virgin he isnt, i really want to have with him but i am nervous?

i have been talking to the same guy for three years and we have hooked up once. he lives in a different state than i do but i am going to see him in a couple months. he really wants to have with me and i really want to also, but i dont want to seem completly clueless. and i also want it to be pleasurable. how can i make this happen?
