Making out while dating

I just left my girlfriend’s house and we were sitting on her couch and starting making out but nothing too intense. This went on for ~5 minutes but towards the end I kinda got aroused but that’s when we decided to stop before things could get anywhere because we are both waiting for marriage. We’re both 18 and have been dating for 5 years if that matters. Should I receive communion tomorrow or should I wait to get to confession. I know I need to try to avoid this in the future.
