FIRST TIME FAIL :/ (update: we did it)

hey all... it's been a rough evening. my boyfriend and i were going to have sex tonight but it didn't end very well. he wasn't able to get it up and it was all downhill from there. i'm so confused you guys... he said it had nothing to do with me and if i believe him but it's not easy to digest when something like this has NEVER happened to me before. this would have been his first time having sex and i really wanted it to be special, i prepared for this moment very carefully. 
i don't know what to do now, i don't want it to be awkward between us but i can't help feeling like it is. i'm feel guilty for being in my feelings and crying about this when he's the one who has to go through something like that. he couldn't even look at me afterwards y'all. i'm so conflicted. i love my boyfriend so very much and i don't want to let this get the best of us but it's not something i ever thought i would have to deal with. 
when we tried talking it out he couldn't really explained what came over him. he's assured me over and over that it isn't my fault and that he is very much ready to have sex. a part of me thinks that he pressure of it all was just getting to his head. idk what to do because this is something i really want to experience with him... any advice? (we're both 17 btw)
UPDATE: IT HAPPENED!!! we tried again and it actually happened and it was just so nice you guys. and like it wasn't crazy wild sex but it was mind blowing it its own simple way and that's all i could ever want.
