Cum in nose

My boyfriend and I haven’t done stuff in about a month and yesterday was finally the day I’d get to go down on him. Well I had been teasing him all day until I finally started to stroke him so i could go down on him... as soon as I was making my way down, he cums and some of it shoots up my nose!!

I thought it was a funny moment but he was so embarrassed! I felt bad but I told him it was okay and that a lot of ppl cum super quick sometimes. I told him that it’s probably because we haven’t done stuff in a while and we’ve been teasing for so long but he still felt so sad. Has this happened to anyone else before? I hate that he feels bad about it, so how can I help him last longer?
