Left a hickey and I feel terrible

Me and my husband just haven’t been connecting on a sexual level. We don’t have sex to have sex we do it cause we feel closer and a connection and we love sharing it together. For probably a year sex had felt more like a chore but a few days ago we had amazing sex! It was so good I accidentally left a hickey on his neck and it’s not like we are teenagers anymore we are adults who have work. Everyone at work made fun of him. I feel absolutely terrible but I haven’t connected with him like that in so long 😭
