Yes, you can get HSV-2 (genital herpes) on the bottom lip through oral sex if there is skin-to-skin contact with an infected area. Herpes simplex virus type 1 (HSV-1), typically associated with cold sores or fever blisters, more commonly affects the mouth and lips. However, it is possible for someone to transmit genital herpes caused by HSV-2 to their partner's mouth during oral-genital contact. If you have concerns about your symptoms or potential exposure to STDs like herpes, consider speaking with a healthcare provider for advice and testing options.
