swollen

just had sex with my boyfriend and i’m confused because i don’t think i’ve ever noticed this before but my labia minora are swollen like especially on the left side and i’m getting scared because i’ve never noticed this before. it’s really sensitive and looks irritated. i will probably just wait a day or 2 to see if the swelling goes down but i’m not sure. anyone else ever had this?? can i do anything about it?
