I have a cut... on my nipple...

Rose

Okay, so my boyfriend and I were fooling around and he loves sucking, biting, and licking my breasts. So I noticed my boob was kind of itchy. I lifted up my top and noticed a very tiny cut which I’m assuming was from when he bit me. I cleaned it, put neosporin on it with a bandaid but does anyone have any other ideas to help get it to heal?
