I just wanna be friends with benefits?

me and my guy friend made out. afterwards he told our mutual guy friend that he thinks he ruined our friendship and he blames himself and yada yada. i told him we were still friends, but he still ignores me. this was like a month ago. but we talked a few times this week. on monday, he was messing with his pencil and he dropped it, twice, and asked me to pick it up. and then yesterday he asked me how to spell permission, even though there were other people around he could've asked. today he was talking about prom and how him and his date are gonna wear black and yellow and i said katy and kody were gonna do that and he said they're copyin me i said idt they know ur doin it cuz then they probly wouldnt he said yeah i'll tell em. and like.. when we talk he usually won't look me in the eye anymore. and the thing is, when we made out, he tried to go further and i wouldn't let him. i'm a good girl, but i really really wanna make out with him again and do other stuff just not sex. i've tried to move on but i can not get the idea of hooking up with him out of my head. he doen't have a gf, i don't have a bf, we're 17, what's the issue? but idk how to tell him this in a way that a.) isn't ridiculously obvious b.) doesn't make him think i like him as more than a friend with benefits and c.) won't make things even worse if he says no, which i don't see why he would, but guys are dumb
