just raw or an infection?

my boyfriend and i had sex like 4 times a few days ago and ever since then my vagina has hurt so bad. its so sensitive and it stings like a b**** when i pee or anything like even move around. it doesnt sting from the urethra but more like from the pee touching the raw parts? it looks really irritated at the bottom area, could that just mean im really raw from having sex so many times? ive googled things which is an awful idea bc now im paranoid and think i have a staph infection or something. i just really want it to go away!!! it hurts whenever i do anything!!! calling my gyno tomorrow
