My Boyfriend And I Were Having Oral Sex Via Rubbing

My boyfriend and i were having oral sex via rubbing on each other with clothes on then to me in my underwear and him with pants on , my clitoris felt fine and wasn't in any pain after until i used the bathroom . I noticed it hurt to sit and i felt uncomfortable in jeans, when i got home and looked i noticed that the skin thats usually around my clit isnt there and its red and sensitive to the touch, should i be worried or will it heal over time?
