Just Another Hookup Night

So I broke up with my long-term girlfriend last week and have been out having fun again. Last night, a friend set me up on a blind date that didn't go well, but afterwards we ended up at a bar where I met someone really attractive. We talked for a bit, shared our phone numbers, and then went back to her place. Next thing you know, we were fooling around in her bed. It wasn't anything serious or planned, just one of those spontaneous moments. I'm not sure if this is normal after being single for so long. Am I rushing into things again? What do you guys think?
