Blunt Sex with No Regrets

Last night, I was out at a party and met a guy who's also into open relationships. We went back to his place, had some drinks, and before we knew it, we were tangled up in each other on the bed, he’s twenty-two, me twenty-five. He slid inside of me without warning, hitting all my spots, and I lost myself completely. His hips slammed against mine with rough abandon as our fingers gripped for purchase. Did this kind of spontaneous sex feel right to others? Is it normal to get so swept away like that?
