Accidental 🍑

So, my boyfriend and I were a little tipsy yesterday and having some fun, rough sex. He was behind me, and when he slipped out once, he accidentally went full speed into my butt. You should know I’ve never done anal before and I definitely wasn’t prepared for it, so I immediately curled up into a ball and started crying. It gave me such an emotional reaction that I cried and had to go lie down for an hour. I know that he didn’t do it on purpose and he feels really horrible about it happening, but I still feel icky today. Has anyone else had a similar experience? Is this a normal response?
