Nervous wreck. Pimple or something else ?!?!

Okay so lip pimple or cold sore ? So yesterday I found out that I had a yeast infection and my boyfriend came over. We didn’t do anything but he rubbed his penis along my mouth. After we left the house I put on some a&d ointment and noticed the bump in the corner of my lip. Then this morning I woke up and noticed the bump above my lip. Can this have anything to do with his penis ?
