Will a virgin enjoy ?

so me and my girlfriend have been together for a while and we want to lose it to eachother. Yes, we are both virgins and i really dont want it to hurt her the first time. will the pain..... decrease if i do oral first and get her ready? will she enjoy oral if shes still a virgin im pretty sure she hasnt done any of this. please and thank you 10 points for best answer. i asked this in two different sections but no help.
