My partner couldn't ejaculate 😱🙇🙈

So I've been seeing this guy for a few months now and sex has been great to the point I'm actually having orgasms which has always been a problem with previous partner's.... before tonight we hadn't seen each other for 2weeks due to holidays etc and he came pretty quick as it had been almost a week before that since we last had sex.. so tonight I expected it to be over quite quick again except it was quite the opposite he Couldn't cum 😱🙈 we tried twice and had anal both times too but that didn't work either he says it happens sometimes but I feel he was just saying that to comfort me as I'd expressed my concerns.... please tell me this is normal and it's not infact because of me 😯😐😞
