Sex🤦🏾‍♀️

My boyfriend and I tried to have sex for the first time but it wouldn’t fit in at all. I’m starting to think it was because he ate my out first and I had an orgasm and it wasn’t planned and I just feel awful. Is this normal?? We are going to try again but without me having an orgasm first and to make it more wet because it was dry. If you have any tips please comment
