my boyfriend fingered me almost three times 2 day... after, i went to the washroom to pee and it burnt just a bit.. so i put my finger on the opening of my vagina and it stung.. so i took a tissue and placed it in the same spot.. right underneath the hole of my vagina.. and there was a tiny speck of blood...(i'm guessing there was some kind of tearing on the outer part of my vagina) is this normal?? should i be worried?? what should i do?? plzz help!!
