REALLY EMBARRASSING 🤭

Yesterday me and my partner had sex for the first time and it was amazing🤤. As we were having sex I started squirting but I thought I was peeing so I pushed him off of me really hard and went to the bathroom. I was so scared that I peed on him that I told him I wanted to stop having sex and I basically ran out of his house🤦🏾‍♀️. I went back over his house but now he wants me to explain what happened that day but I’m so nervous and embarrassed to tell me😭 how should I tell him😩
