Fwb: how to ask

Me and this guy recently decided we wanted to be fwb. He lives about 40-45min away from me and since he has his own house (I don’t) I go to his place. I don’t mind the drive but for what it’s worth I don’t think it’s worth the drive. He’s great and all but the two times we’ve had sex it was only one round each time. I’ve given him head and he hasn’t done that to me🥲 You’d think since I’m driving almost an hour away he’d want to go more rounds and such but idk. I guess it’s not too bad cause he lets me stay over after and watch tv with him rather than being like okay bye right after sex but Idk how to tell him like if we can go more rounds or if he even likes to give oral
